Needed since rootfs is now read-only
Rabbitmq needs to be able to write to the fs at /var/lib/rabbitmq. It may be possible to get rid of the initContainer and use fsGroup in the pod securityContext to manage this, but that does not work for the hostVolume mounts I use for dev. The solution here moves the actual mount to the rabbitmq/ directory in the rabbitmq-data volume and uses an initContainer to set the permissions on that. That should work for any volume type.

Sets securityContexts for the rabbitmq pod so it does not run as root.
This creates a permissions issue with the
rabbitmq-datavolume, which is mounted at/var/lib/rabbitmq. The permissions on that volume require root, at least with thehostPathdriver I use in my dev testing. I tried usingfsGroupin the podseurityContextto fix this but that does not seem to work withhostPath. While it might work for production use, I've instead added aninitContainerto create a subdirectory in therabbitmq-datavolume with the necessary permissions, then mount this viasubPathat/var/lib/rabbitmq.
