Since the CloudStack virtual router was redesigned on version 4.6 it has been observed that the DHCP leases file is not persistent across network operations. This causes conflicts on guest VMs static IPs, causing these static IPs to not be renewed by the DHCP server running on isolated and VPC networks' virtual routers (dnsmasq). On stopping or destroying a VM, its dhcp/dns records are not removed from the virtual router causing ghost effects.

With this patch b766bf7
we started tracking disks in attaching state so that other attach request can fail gracefully. However this missed the case where disks were in allocated state but attach was requested.
For the use case where users want to attach disk in allocated state but not ready, we need to have allocated-attaching transition as well. We must take care of returning to the original state - allocated or ready - when attach request has completed.
For the use case of unstarted vm's the disk must proceed as follows - "Allocated" -> Attaching -> Allocated. When VM is started, the disk is "created" and pool is assigned. For the use case of started VMs it's more trivial and disk proceeds as follows - Ready -> Attaching -> Ready.
Test this by creating a VM with "startvm=false", create a disk and try attaching it in allocated state. It would give an exception on latest 4.11 but will be fixed on this patch.

* The snapshot.backup.rightafter configuration variable was removed by:
SHA: 6bb0ca2f854
This adds it back, though named snapshot.backup.to.secondary now instead.
This global parameter, once set, will allow you to prevent automatic backups of
snapshots to secondary storage, unless they're actually needed.

A corner case was found on 4.11.2 for #2493 leading to an infinite loop in state PrepareForMaintenance
To prevent such cases, in which failed migrations are detected but still running on the host, this feature adds a new cluster setting host.maintenance.retries which is the number of retries before marking the host as ErrorInMaintenance if migration errors persist.
How Has This Been Tested?
- 2 KVM hosts, pick one which has running VMs as H
- Block migrations ports on H to simulate failures on migrations:
iptables -I OUTPUT -j REJECT -m state --state NEW -m tcp -p tcp --dport 49152:49215 -m comment --comment 'test block migrations' iptables -I OUTPUT -j REJECT -m state --state NEW -m tcp -p tcp --dport 16509 -m comment --comment 'test block migrations
- Put host H in Maintenance
- Observe that host is indefinitely in PrepareForMaintenance state (after this fix it goes into ErrorInMaintenance after retrying host.maintenance.retries times)
The view "service_offering_view" doesn't include removed SOs, as a result when SO is removed, the bug happens. The PR introduces a change for resource calculation changing "service_offering_view" to "service_offering" table which has all service offerings.
Must be fixed in:

This force stops old VRs when performing rolling restart with
cleanup=true. This will ensure that VRs are powered off quickly than
wait longer for the normal ACPI shutdown. During testing, it was found
on VMware where VM stops are slow compared to XenServer and KVM.

This fixes#2719 where private gateway IP might be incorrectly
programmed on a guest network nic. The VR would now check ipassoc
requests by mac addresses than provided nic/device id in case they are
wrong.
The root cause is that the device id information is lost when aggregated
commands are created upon starting of a new VPC VR, without the correct
device id in ip_associations json it mis-programs the VR.

VMware router will be rebooted based on #2794, per current config
the VRs on reboot will go through fsck checks slowing down the deployment
process by few seconds. This will ensure that fsck checks are done
on every 3rd boot of the VR. The `4` is used because 1st boot is done
during the build of systemvmtemplate appliance.

* CLOUDSTACK-9473: storage pool capacity check when volume is resized or migrated
Storage pool checker is not being called on resize and migrate volume.
This may lead to allocated percentage of storage above 100%.
Setup:
1 VMware cluster with 2 Hosts.
Executed Steps:
Applied the following global settings:
storage.overprovisioning.factor = 1
pool.storage.allocated.capacity.disablethreshold = 1
pool.storage.capacity.disablethreshold = 1
Restarted management server
Executed Resize and migrate pool and Observed that Storage pool checker is not performed on resizeVolume and migrateVolume.
Result:
Root cause analysis shows storage pool checker is not called when doing migration and resizing.

In integration work for CCS I found that the service call UserVmService.destroyVm(long uuid, boolean expunge) does not honour the expunge flag. I traced it down to the implementation VirtualMachineManagerImpl.destroy(String vmUuid, boolean expunge).
Testing: manual testing so far, testing will pose some crosscutting challanges as the behaviour and implementation are seperated by about five layers of abstraction.
Fixes the version in pom etc. to be consistent with versioning pattern as X.Y.Z.0-SNAPSHOT after a minor release.

Changes in PR #2508 have caused network restart to fail in a Nuage setup,
as the new VR takes the same IP as the old one, and the old VR is still running.
Nuage doesn't support multiple VM's having the same IP.
We delay provisioning the interfaces in VSD until the old VR interface is released.

* fix encoding for base64 to StandardCharsets.US_ASCII
* fix MockServerTest.testIsMockServerCanUpgradeConnectionToSsl()
This is another method that is causing Jenkins to fail for almost a month
Example: A VM that uses managed storage is stopped. The VM is then started on a different host in the same cluster. The Start operation fails.
To get around this issue, you must either start the VM up on the same host or on a host in a different cluster.
The reason is due to a slightly erroneous check in VolumeOrchestrator.prepare.
To solve this issue, we should be checking if the cluster ID changes, not if the host ID changes.
This introduces a new global setting `vm.configdrive.primarypool.enabled` to toggle creation/hosting of config drive iso files on primary storage, the default will be false causing them to be hosted on secondary storage. The current support is limited from hypervisor resource side and in current implementation limited to `KVM` only. The next big change is that config drive is created at a temporary location by management server and shipped to either KVM or SSVM agent via cmd-answer pattern, the data of which is not logged in logs. This saves us from adding genisoimage dependency on cloudstack-agent pkg.
The APIs to reset ssh public key, password and user-data (via update VM API) requires that VM should be shutdown. Therefore, in the refactoring I removed the case of updation of existing ISO. If there are objections I'll re-put the strategy to detach+attach new config iso as a way of updation. In the refactored implementation, the folder name is changed to lower-cased configdrive. And during VM start, migration or shutdown/removal if primary storage is enable for use, the KVM agent will handle cleanup tasks otherwise SSVM agent will handle them.

When a user shuts down their VM from the guest OS (and VM HA is enabled), the VM just powers itself back on. Our environment is on KVM hosts.
CloudStack does not know the difference between a VM failing or being shutdown from within the guest OS.
This is a major pain point for all our users - especially since they don't pay for VMs when they are shutoff. It is not intuitive for end-users to understand why they can't shutdown VMs from within the guest OS. Especially when they all come from (non-cloudstack) VMware and Hyper-V environments where this is not an issue.
However, if a host fails, we need VM HA to still work.
This PR that creates a configuration option "ha.vm.restart.hostup". With this option set to false, if CloudStack sees a VM shutdown out-of-band, but the host it was on is still online, then it won't power the VM back on. The logic is that since the host is online, it was most likely shutdown from the guest OS.
For when a host actually fails, standard VM HA logic takes over and powers on VMs (if they have VM HA enabled) if the host they were on fails.
If that "ha.vm.restart.hostup" option is true (the default to match current functionality), it works like always, and even in-guest shutdowns of VMs causes CloudStack to power back on the VM.
* Primary Storage count for an account does not decrease when a Data Disk is deleted
When a data disk is created and not attached in a running VM, the "deleteVolume" will not decrement the count for used primary storage in the VMs accounting information. The property that is not being decremented is called "primarystoragetotal"; this information can be retrieved via "listAccounts" API method.
Steps to reproduce this issue:
1 - Create an account, deploy a VM in it
2 - Check the primary storage count for the account with listAccounts API
3 - Create a data disk
4 - Check the primary storage count for the account with listAccounts API
5 - Delete the Data disk
6 - Check the primary storage count for the account with listAccounts API - It is the same as before deleting the data disk (it should not be the same as the value in step 2!)

* CLOUDSTACK-9184: Fixes#2631 VMware dvs portgroup autogrowth
This deprecates the vmware.ports.per.dvportgroup global setting.
The vSphere Auto Expand feature (introduced in vSphere 5.0) will take
care of dynamically increasing/decreasing the dvPorts when running out
of distributed ports . But in case of vSphere 4.1/4.0 (If used), as this
feature is not there, the new default value (=> 8) have an impact in the
existing deployments. Action item for vSphere 4.1/4.0: Admin should
modify the global configuration setting "vmware.ports.per.dvportgroup"
from 8 to any number based on their environment because the proposal
default value of 8 would be very less without auto expand feature in
general. The current default value of 256 may not need immediate
modification after deployment, but 8 would be very less which means
admin need to update immediately after upgrade.
