CLOUDSTACK-6399: When there are no vms running on hyperv host, then agent was returning null. In
that case cloudstack was not doing anything and not updating the state of the vms to stopped.
Now the agent returns empty list of hostvmstatereport. Management server will then update the
vm state to stopped (instead of not acting upon the return state).
CLOUDSTACK-6620: Fixed null pointer exception in hyperv agent in getting vmstats, when all vms are deleted from outside
CLOUDSTACK-6622: After a volume was live migrated, the destination smb storage path was added to
the folder column. For an smb share the smb credentials are in the query string of the path.
Before adding the path, smb shares query string should be cleaned up.
