We've occasionally seen environments where LXCFS is having a bit of a hard time and crashes.
Those crashes then effectively break every single instance on the system, requiring all containers be restarted.

To mitigate that, LXCFS 6.0.1 has grown support for running multiple instances of itself on the system.
We should add support for that with a server-wide config key controlling whether we want LXCFS to be shared (default) or be run per-instance.

This will come with a tiny increase in instance startup/shutdown time as well as running an additional process for each instance on the system and associated kernel cost for the FUSE connection and mount table entries.
