This reverts "9ee129ae6a08935645734ad520bec72bf5f22217" from #3525, as
the solution is not optimal and would cause a single Link to be added
in the Map if management server is behind a LB.

Every time a client connects, the NioServer will retain the link against
the InetSocketAddress object. If the same agent/client reconnects, it
will grow older links over time and in case of denial of service attack
or a client/script/monitoring-service reconnecting aggressively against
port 8250 will cause the `_links` weak hashmap to grow over time and
very quickly.
The fix will ensure that only one Link gets weakly retained for an
incoming client based on its address string.

* server: Do NOT cleanup dhcp and dns when stop a vm
According comment in PR #3608, dhcp and dns entries are cleaned up only when a VM is expunged.
Revert part of commit 8fb388e9312b917a8f36c7d7e3f45985a95ce773.
* server: cleanup dns/dhcp entries in removeNic instead of finalizeExpunge
* kvm/security_group: Make Security Group Python 3 compatible
This script only runs on the KVM Hypervisors and these all support
Python 3.
As Python 2 is deprecated at the end of 2019 we need to fix these
scripts to work under Python 3.
CentOS 7, 8 and Ubuntu 16.04 and 18.04 all have Python 3 installed
by default.
Ubuntu 20.04 will no longer have Python 2 installed and therefor
this script needs to be modified to work with Python 3.

* Add dependency of python3 in packaging/centos7/cloud.spec
This fixes a behaviour to not cleanup DHCP and DNS rules for NICs of a
VM in the VR when it is stopped, but instead when VM is expunged because
stopped VMs in CloudStack still retain the IPs and records.

Refactor: Cleanup duplicate code
Make use of Java 8 default implementation in interfaces,
to remove code duplication between XxxCmd and XxxCmdAsAdmin.
Refactor checkFormat by pre-calculating the supported
extensions. Also make use of this in ImageStoreUtil.
Makes it easier to add new file and compression formats.
Logrotate should only touch security_group.log and resizevolume.log
as the agent.log is already rotated by log4j inside the Agent.
Having two systems trying to rotate agent.log leads to all kinds of
issues like having binary (compressed) data in the middle of a plain-text
log file.
In addition we do not have to rotate the logs every day, only when they
grow larger than 10M. On fairly idle hypervisors this should not cause
those logs to rotate every day.

Using this tool on a hypervisor admins can query KVM Instances running
on that hypervisor if they have the Qemu Guest Agent installed.
All System VMs have this and they can be queried.
For example:
$ cloudstack-guest-tool i-2-25-VM

When a network IP range is removed, the "vlan" stays mapped on pod_vlan_map; therefore, the method that lists the VLANs by pod id will return null VLANS.
This PR adds proper verifications to avoid null pointer exception when deploying VRs on a pod with removed VLANs. The exception was caused on getPlaceholderNicForRouter.
Problem: In Vmware, appliances that have options that are required to be answered before deployments are configurable through vSphere vCenter user interface but it is not possible from the CloudStack user interface.
Root cause: CloudStack does not handle vApp configuration options during deployments if the appliance contains configurable options. These configurations are mandatory for VM deployment from the appliance on Vmware vSphere vCenter. As shown in the image below, Vmware detects there are mandatory configurations that the administrator must set before deploy the VM from the appliance (in red on the image below):
Solution:
On template registration, after it is downloaded to secondary storage, the OVF file is examined and OVF properties are extracted from the file when available.
OVF properties extracted from templates after being downloaded to secondary storage are stored on the new table 'template_ovf_properties'.
A new optional section is added to the VM deployment wizard in the UI:
If the selected template does not contain OVF properties, then the optional section is not displayed on the wizard.
If the selected template contains OVF properties, then the optional new section is displayed. Each OVF property is displayed and the user must complete every property before proceeding to the next section.
If any configuration property is empty, then a dialog is displayed indicating that there are empty properties which must be set before proceeding
image
The specific OVF properties set on deployment are stored on the 'user_vm_details' table with the prefix: 'ovfproperties-'.
The VM is configured with the vApp configuration section containing the values that the user provided on the wizard.
This PR fixes range check in VM deployment wizard while using custom constrained offering.
Existing code was failing while checking user input value in the form for CPU cores and RAM size when minimum and maximum value vary in digit count.
Also, while re-selecting offerings slider position was not restored to minimum value. THis has been fixed with changes.

Fix regression bug that affects KVM local storage migration. Some of the desired execution flows for KVM local storage migration had been altered to allow only managed storage to execute. Fixed allowing managed and non managed storages to execute.
Fixes#3521
This reverts commit 7a27e35a612f13a0ce43459b22e01d9b69627220.
We're near 4.13 RC1, we've low confidence if the changes from #3152
would cause other regressions so reverting this. The author may send a
PR again towards 4.14.
Regressions found are all related to template and iso registration and
upload.
Fixes:
- This allows getUploadParamsForIso for all user role types, also fixes
authorised field for getUploadParamsForTemplate API.
- Fix global setting description to say what is used when value is empty/blank.
- For VM running/allocated usage description, use parenthesis to return the instance name and ID.
- Display template download progress when template is added to a project

Retrieval of an image store using ImageStoreProviderManager has been refactored by introducing three different methods,
DataStore getRandomImageStore(List<DataStore> imageStores);
To get an image store for reading purpose. Threshold capacity check will not be used here.
DataStore getImageStoreWithFreeCapacity(List<DataStore> imageStores);
To get an image store for reading purpose. Threshold capacity check will be used here and the store with max free space will be returned. If no store with filled storage less than the threshold is found, the NULL value will be returned.
List<DataStore> listImageStoresWithFreeCapacity(List<DataStore> imageStores);
To get a list of image stores for writing purpose which fulfills threshold capacity check.
Correspondingly DataStoreManager methods have been refactored to return similar values for a given zone.
Fixes#3287 - NULL value will be returned when secondary storage is needed for writing but there is not store with free space.
Fixes#3041 - Rather than returning random secondary storage for writing, storage with max. free space will be returned.
Fixes#3478 - For migration on VMware, all writable secondary storage will be mounted while preparation.

1. Fix populating g_allowUserViewAllDomainAccounts flag. This was
implemented incorrectly and caused flag's effect to not reflect

2. Filter account/project names only for add operation. update

removal of any account that could have had permissions but allows
only adding accounts/projects which are in caller's domain.
3. Added some checks where null variable could result in crash.

There are certain scenarios where the 169.254.0.0/16 subnet is used for different
purposes then CloudStack on a hypervisor.
Once of such scenarios is a BGP+EVPN+VXLAN setup using BGP Unnumbered where the
169.254.0.1 address is used by Frr/Zebra BGP routing to send traffic to the
neighboring router.
The following settings can be changed in the agent.properties (default values added):
control.cidr=169.254.0.0/16
Make sure the global setting 'control.cidr' matches the values defined in the agent.propeties!
In the future the mgmt server can send this parameter to a KVM Agent on startup, but at the moment
this framework is not in place and thus these values can't be send to the Agent in a proper manner.

Currently when refreshing disk usage stats all kvm agents are asked to collect stats for all volumes. In setups with multiple kvm hosts where managed storage is used, not all volumes are attached to all kvm hosts, this results in a large number of warnings in the kvm agent logs. This change introduces a filter step in case managed storage is used so that the management server only requests kvm agents for stats about volumes that are connected to each kvm host.
Fixes checkstyle issue caused by previous commit 6a511fce40f5363d71c5515df9841c2493c73c31
