PWX-36511 Expose API to return a set of nodes that can be upgraded in parallel #2440

Closed adityadani closed 6 months ago

What this PR does / why we need it:
This API takes an input list of nodes from which the server will return a set that doesn't have any common volume within them. This ensures that if these nodes are upgraded at once, then a volume with 1+ replica has at least one replica somewhere which will be up.
