Protect multiple VMFS VMs

Multiple VMFS VMs can be added to a Protection Group at group-level consistency.

Assume a scenario where the VMDKs of VMs are not from a single datastore. The OS disk of VM1 is on Datastore1 and the data disk is on Datastore2. To make this VM consistent, snapshot has to be created at the same time for both the datastores. In this scenario, use the group-level consistency.
