If the resource state of hypervisor in "Maintenance" then it
should be considered as offline even though the agent state
is "Up". Since its in maintenance mode, it cant be used to
allocate VM's and hence can't be considered towards resource
allocation
If vm has last host_id specified, cloudstack will try to start vm on it at first.
However, host tag is checked, but guest os preference is not checked.
for new vm, it will be deployed to the preferred host as we expect.

* Display acl name in listNetworks response
Display acl name along with its id so that we
dont need to make extra api call to get acl name
* Add since tag
After a few hours running with InfluxDB configured, CloudStack hangs due to OutOfMemoryException raised. The exception happens at com.cloud.server.StatsCollector.writeBatches(StatsCollector.java:1510):

Context on InfluxDB Batch: Enabling batch on InfluxDB is great and speeds writing but it requires caution to avoid Zombie threads.
Solution: This happens because the batching feature creates an internal thread pool that needs to be shut down explicitly; therefore, it is important to add: influxDB.close().
When executing request assignVirtualMachine with null domainID and a valid projectID then a NullPointerException happens at DomainChecker.java.
Command example:
assign virtualmachine virtualmachineid=vmID projectid=projectID account=admin
The NullPointerException that is thrown at DomainChecker is handled at AssignVMCmd.java#L142, resulting in the following log message: Failed to move vm null.
While remove secondary nic from a Running vm, if update the default nic to the secondary nic before the nic is removed, the vm will not have default nic (and cannot be started) when both operations are completed.
It is because UpdateDefaultNic api is not handled as a vm work job (AddNicToVMCmd and RemoveNicFromVMCmd are), it is processed before nic is removed. The result is that secondary nic becomes default nic and got removed.
