music-assistant: Initial deployment

_Music Assistant_ is pretty straightforward to deploy, despite
upstream's apparent opinion otherwise.  It just needs a small persistent
volume for its media index and customization.  It does need to use the
host network namespace, though, in order to receive multicast
announcements from e.g. AirPlay players, as it doesn't have any way of
statically configuring them.
