CLOUDSTACK-9175: [VMware DRS] Adding new host to DRS cluster does not
participate in load balancing.
Summary: When a new host is added to a cluster, Cloudstack doesn't create
all the port groups (created by cloudstack earlier in other hosts) present in
the cluster. Since the new host doesn't have all the necessary networking port
groups of cloudstack, it is not eligible to participate in DRS load balancing
or HA.
Solution: When adding a host to the cluster in Cloudstack, use VMware API
to find the list of unique port groups on a previously added host (older host
in the cluster) if exists and then create them on the new host.
