Scenario:
Daemon is ungracefully shutdown and leaves plugins running (no
live-restore).
Daemon comes back up.
The next time a container tries to use that plugin it will cause a
daemon panic because the plugin client is not set.
This fixes that by ensuring that the plugin does get shutdown.
Note, I do not think there would be any harm in just re-attaching to the
running plugin instead of shutting it down, however historically we shut
down plugins and containers when live-restore is not enabled.

Ensures that when a plugin is removed that it doesn't interfere with
other plugins mounts and also ensures its own mounts are cleaned up.
