The default GC algorithm G1 that is enabled by default with Java11
serves well on multiprocessor machines with large amount of memory where
GC is probablistic with low pauses, where response time is more
important than throughput and GC is kept shorter.
The CloudStack management server is largely a multi-threaded server
application that handles and orchestrates several network requests, and
has the default max. heap size of only 2G that can be considered a
small/medium application from a heap size perspective. Perhaps a more
aggresive GC algorithm such as ParallelGC as used in Java8 and before
(that is previous CloudStack releases) would serve better for throughput
and cause more aggresive GC.

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
We should have the metrics for the hosts which are dedicated to certain domains.
We should also be able to see cpu/memory/storage currently used per domain
> How Has This Been Tested?
Enable prometheus server
Add 127.0.0.1 as allowed Ip so that you can fetch metrics from prometheus
Now fetch the endpoint
# http http://127.0.0.1:9595/metrics | grep cloudstack_host_is_dedicated
cloudstack_host_is_dedicated{zone="mgt122-10",hostname="node11",ip="10.13.122.11"} 1
# http http://127.0.0.1:9595/metrics | grep cloudstack_host_dedicated_to_account
cloudstack_host_dedicated_to_account{zone="mgt122-10",hostname="node11",ip="10.13.122.11"} 1

* Added worker VM hardware version when creating a template from a volume and migrating a detached volume
* Add null parameter back that was removed by merge
It is not common, but HTTP requests can fail due to connection issues. In order to mitigate such situations and also improve logging, this PR enhances the Redfish request handling by adding an execution flow for re-trying HTTP requests; the retry happens only if the global settings redfish.retries is set to 1 or more retries; default is of 2 (two). One can disable the retries by setting redfish.retries to 0 (zero).
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.
Fixes: #3554 (comment)
Since Java 9 the notation 'address=port' only applies to localhost.
For remote debug you have to explicitly specify that you want to listen
to all IP addresses (e.g. address=*8000)
VMware code keeps a cache of existing VMs on a hypervisor host using cloud.vm.internal.name property of the VM. Searching for unmanaged instances/VMs on a host might not return an expected result when this property differs from the actual name of the VM.

In large environments, with VR having multiple nics when plugging in
nic, it must get existing nics by sorted device ID otherwise it may
cause incorrect nic plugging/order.
