enable podman-remote volume prune

allow users to remotely prune volumes.

this is the last volume command for remote enablement.  as such,
the volume commands are being folded back into main because they
are supported for both local and remote clients.

also, enable all volume tests that do not use containers
as containers are not enabled for the remote client yet.
