CLOUDSTACK-6865 , CLOUDSTACK-6868: [hyperv] while attaching the volume we were changing the volume's Image format to hypervisor's default Image format, hence it was failing to find the volume with vhdx format. Now changed the behavior to set Image Format for volume only when it is not set
CLOUDSTACK-6867: Added option to upload the volume in VHDX format
CLOUDSTACK-6872: [hyperv] removed the redundant connectToRemote, DisconnectRemote methods which in turn fixes this bug. connectToRemote was used to connect to share, but once the share is domain joined we don't need this method as we already have required permissions
