The 'force' parameter of os-brick's disconnect_volume() method allows
callers to ignore flushing errors and ensure that devices are being
removed from the host.

We should use force=True when we are going to delete an instance to
avoid leaving leftover devices connected to the compute host which
could then potentially be reused to map to volumes to an instance that
should not have access to those volumes.

We can use force=True even when disconnecting a volume that will not be
deleted on termination because os-brick will always attempt to flush
and disconnect gracefully before forcefully removing devices.

Also did a bit of cleanup in the text message to tell *when* we need to bump
the min service version.
Given 2023.1 is our first SLURP release, we need to clarify the level of
support we now have for rolling upgrades.

Next cycle, we should update the min version to be Zed.
