There are two scenarios of logging which needs refactoring/improvement:
Method invocation replaced by variable
This means that in the logging code, the method invocation is pre-defined as a variable. for simplicity, the method invocation should be replaced by the variable.
Delete variable which must be null
The variable in the logging code is null, there is no need to put the variable there.

Support Backup of Snapshots for Managed Storage```
This PR adds an ability to Pass a new parameter, locationType,
to the createSnapshot API command. Depending on the locationType,
we decide where the snapshot should go in case of managed storage.
There are two possible values for the locationType param
1) `Primary`: The standard operation for managed storage is to
keep the snapshot on the device (primary). For non-managed storage, this will
give an error as this option is only supported for managed storage
2) `Secondary`: Applicable only to managed storage. This will
keep the snapshot on the secondary storage. For non-managed
storage, this will result in an error.
The reason for implementing this feature is to avoid a single
point of failure for primary storage. Right now in case of managed
storage, if the primary storage goes down, there is no easy way
to recover data as all snapshots are also stored on the primary.
This features allows us to mitigate that risk.

CLOUDSTACK-9438: Fix for CLOUDSTACK-9252 - Make NFS version changeable in UIJIRA TICKET: https://issues.apache.org/jira/browse/CLOUDSTACK-9438
### Introduction
From #1361 it was possible to configure NFS version for secondary storage mount.
However, changing NFS version requires inserting an new detail on `image_store_details` table, with `name = 'nfs.version'` and `value = X` where X is desired NFS version, and then restarting management server for changes to take effect.
Our improvement aims to make NFS version changeable from UI, instead of previously described workflow.
### Proposed solution
Basically, NFS version is defined as an image store ConfigKey, this implied:
* Adding a new Config scope: **ImageStore**
* Make `ImageStoreDetailsDao` class to extend `ResourceDetailsDaoBase` and `ImageStoreDetailVO` implement `ResourceDetail`
* Insert `'display'` column on `image_store_details` table
* Extending `ListCfgsCmd` and `UpdateCfgCmd` to support **ImageStore** scope, which implied:
** Injecting `ImageStoreDetailsDao` and `ImageStoreDao` on `ConfigurationManagerImpl` class, on `cloud-server` module.
### Important
It is important to mention that `ImageStoreDaoImpl` and `ImageStoreDetailsDaoImpl` classes were moved from `cloud-engine-storage` to `cloud-engine-schema` module in order to Spring find those beans to inject on `ConfigurationManagerImpl` in `cloud-server` module.
We had this maven dependencies between modules:
* `cloud-server --> cloud-engine-schema`
* `cloud-engine-storage --> cloud-secondary-storage --> cloud-server`
As `ImageStoreDaoImpl` and `ImageStoreDetailsDao` were defined in `cloud-engine-storage`, and they needed in `cloud-server` module, to be injected on `ConfigurationManagerImpl`, if we added dependency from `cloud-server` to `cloud-engine-storage` we would introduce a dependency cycle. To avoid this cycle, we moved those classes to `cloud-engine-schema` module

By adding a Random Number Generator device to Instances we can prevent
entropy starvation inside guest.
The default source is /dev/random on the host, but this can be configured
to another source when present, for example a hardware RNG.
When enabled it will add the following to the Instance's XML definition:
<rng model='virtio'>
<rate period='1000' bytes='2048' />
<backend model='random'>/dev/random</backend>
</rng>
If the Instance has the proper support, which most modern distributions have,
it will have a /dev/hwrng device which it can use for gathering entropy.

CLOUDSTACK-9422: Granular 'vmware.create.full.clone' as Primary Storage setting### Introduction
For VMware, It is possible to decide creating VMs as full clones on ESX HV, adjusting `vmware.create.full.clone` global setting. We would like to introduce this property as a primary storage detail, and use its value instead of global setting's value.
We propose introducing `fullCloneFlag` on `PrimaryDataStoreTO` sent on `CopyCommand`. This way we can reconfigure `VmwareStorageProcessor` and `VmwareStorageSubsystemCommandHandler` similar as it was done for `nfsVersion` but refactoring it to be more general.

Adding support for cross-cluster storage migration for managed storage when using XenServerThis PR adds support for cross-cluster storage migration of VMs that make use of managed storage with XenServer.
Managed storage is when you have a 1:1 mapping between a virtual disk and a volume on a SAN (in the case of XenServer, an SR is placed on this SAN volume and a single virtual disk placed in the SR).
Managed storage allows features such as storage QoS and SAN-side snapshots to work (sort of analogous to VMware VVols).
This PR focuses on enabling VMs that are using managed storage to be migrated across XenServer clusters.
I have successfully run the following tests on this branch:
TestVolumes.py
TestSnapshots.py
TestVMSnapshots.py
TestAddRemoveHosts.py
TestVMMigrationWithStorage.py (which is a new test that is being added with this PR)

CLOUDSTACK-9428: Fix for CLOUDSTACK-9211 - Improve performance of 3D GPU support in cloud-plugin-hypervisor-vmwareJIRA TICKET: https://issues.apache.org/jira/browse/CLOUDSTACK-9428
### Introduction
On #1310 passing vRAM size to support 3D GPU problem was addressed on VMware. It was found out that it could be improved to increase performance by reducing extra API calls, as we'll describe later
### Improvement
On WMware, `VmwareResource` manages execution of `StartCommand.` Before sending power on command to ESXi hypervisor, vm is configured by calling `reconfigVMTask` web method on vSphere's client `VimPortType` web service.
It was found out that we were using this method 2 times when passing vRAM size, as it implied creating a new vm config spec only editing video card specs and making an extra call to `reconfigVMTask.`
We propose reducing the extra web service call by adjusting vm's config spec. This way video card gets properly configured (when passing vRAM size) in the same configure call, increasing performance.
### Use case (passing vRAM size)
* Deploy a new VM, let its id be X
* Stop VM
* Execute SQL, where X is vm's id and Z is vRAM size (in kB):
````
INSERT INTO cloud.user_vm_details (vm_id, name, value) VALUES (X, 'mks.enable3d', 'true');
INSERT INTO cloud.user_vm_details (vm_id, name, value) VALUES (X, 'mks.use3dRenderer', 'automatic');
INSERT INTO cloud.user_vm_details (vm_id, name, value) VALUES (X, 'svga.autodetect', 'false');
INSERT INTO cloud.user_vm_details (vm_id, name, value) VALUES (X, 'svga.vramSize', Z);

Often, patch and security releases do not require schema migrations or
data migrations. However, if an empty upgrade class and associated
scripts are not defined, the upgrade process will break. With this
change, if a release does not have an upgrade, a noop DbUpgrade is added
to the upgrade path. This approach allows the upgrade to proceed and
for the database to properly reflect the installed version. This change
should make the release process simpler as RMs no longer need to
rememeber to create this boilerplate code when starting a new release.
Beginning with the 4.8.2.0 and 4.9.1.0 releases, the project will
formally adopt a four (4) position release number to properly accomodate
rekeases that contain only CVE fixes. The DatabaseUpgradeChecker and
Version classes made assumptions that they would always parse and
compare three (3) position version numbers. This change adds the
CloudStackVersion value object that supports both three (3) and four (4)
version numbers. It encapsulates version comparsion logic, as well as,
the rules to allow three (3) and four (4) to interoperate.
* Modifies DatabaseUpgradeChecker to handle derive an upgrade path for
a version that was not explicitly specified. It determines the
releases the first release before it with database migrations and uses
that list as the basis for the list for version being calculated. A
noop upgrade is then added to the list which causes no schema changes
or data migrations, but will update the database to the version.
* Adds unit tests for the upgrade path calculation logic in
DatabaseUpgradeChecker
* Removes dummy upgrade logic for the 4.8.2.0 introduced in previous
versions of this patch
* Introduces the CloudStackVersion value object which parses and
compares three (3) and four (4) position version numbers. This class
is intended to replace com.cloud.maint.Version.
* Adds the junit-dataprovider dependency -- allowing test data to be
concisely generated separately from the execution of a test case.
Used extensively in the CloudStackVersionTest.

We noticed that when an exception occurs within the cleanup loop inside
the deletePhysicalDisk routine that the previously allocated contexts
are not cleaned up. This seemed to cause an eventual crash of the host
agent after multiple exceptions within the loop.
In addition to ensuring the contexts are always freed we also improved
the logging when exceptions do occur to include the actual return code
from the underlying library in deletePhysicalDisk and deleteSnapshot.

CLOUDSTACK-9368: Fix for Support configurable NFS version for Secondary Storage mounts## Description
JIRA TICKET: https://issues.apache.org/jira/browse/CLOUDSTACK-9368
This pull request address a problem introduced in #1361 in which NFS version couldn't be changed after hosts resources were configured on startup (for hosts using `VmwareResource`), and as host parameters didn't include `nfs.version` key, it was set `null`.
## Proposed solution
In this proposed solution `nfsVersion` would be passed in `NfsTO` through `CopyCommand` to `VmwareResource`, who will check if NFS version is still configured or not. If not, it will use the one sent in the command and will set it to its storage processor and storage handler. After those setups, it will proceed executing command.

Dynamically load drivers before creating our DB connectionsSolution to the mailing thread titled "MySQL : No suitable driver found for jdbc:mysql".
It doesn't harm that we explicitely load the MySQL driver, and for those which would use a commons-dbcp version < 1.4 this would fix it as well. Since JDBC 4.0, the JDBC driver can auto-register itself, but for some weird cases (like ours), it's not working. Therefore we need to explicitly load the JDBC driver.

Remodeling of Nuage VSP Plugin + CLOUDSTACK-9294Hi all,
We've remodeled the Nuage VSP plugin to use the same model as VMWare is using (non-OSS). Before, we had a runtime dependency to the Nuage Client, this has been changed to a compile-time dependency instead because of multiple reasons (build management, readability, maintainability, ...)
We've adapted the code so it now uses model objects defined in the Nuage client instead of passing a list of parameters to the Nuage client. This is a lot more readable, and a lot more maintainable.
I've had a chat with @DaanHoogland about this approach, and he told me that ACS is trying to move away from the whole non-OSS approach. We're looking into the Juniper approach, we would set up a custom maven repository which would host the required dependencies for the Nuage VSP plugin.
Any remarks or suggestions are always welcome :)

Taking fast and efficient volume snapshots with XenServer (and your storage provider)A XenServer storage repository (SR) and virtual disk image (VDI) each have UUIDs that are immutable.
This poses a problem for SAN snapshots, if you intend on mounting the underlying snapshot SR alongside the source SR (duplicate UUIDs).
VMware has a solution for this called re-signaturing (so, in other words, the snapshot UUIDs can be changed).
This PR only deals with the CloudStack side of things, but it works in concert with a new XenServer storage manager created by CloudOps (this storage manager enables re-signaturing of XenServer SR and VDI UUIDs).
I have written Marvin integration tests to go along with this, but cannot yet check those into the CloudStack repo as they rely on SolidFire hardware.
If anyone would like to see these integration tests, please let me know.
