    <#
    .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.
