    <#
    .SYNOPSIS
      Updates the volume group on a FlashArray for a VVol-based VM.
    .DESCRIPTION
      Takes in a VM and a FlashArray connection. A volume group will be created if it does not exist, if it does, the name will be updated if inaccurate. Any volumes for the given VM will be put into that group.
    .INPUTS
      FlashArray connection, a virtual machine.
    .OUTPUTS
      Returns the FlashArray volume names of the input VM.

    PS C:\ Mount-PfaVvolDatastore -datastore $datastore -flasharray $flasharray -cluster (get-cluster MyCluster)
 
    Connects a protocol endpoint to a cluster and then mounts the specified existing VVol datastore to that cluster.
  .EXAMPLE
    PS C:\ $flasharray = new-pfaConnection -endpoint flasharray-m50-1 -credentials $creds -ignoreCertificateError -nonDefaultArray
    PS C:\ Mount-PfaVvolDatastore -datastore $datastore -flasharray $flasharray -cluster (get-cluster MyCluster) -datastoreName m50-VVolDs
 
    Mounts the default VVol datastore of the specifed FlashArray to the cluster.
  .EXAMPLE
    PS C:\ $vasaArray = get-vasaStorageArray m50-1-pure
    PS C:\ Mount-PfaVvolDatastore -vasaArray $vasaArray -cluster (get-cluster MyCluster)
 
    Mounts the default VVol datastore of the specifed FlashArray to the cluster.
