* ci: securityContext for rabbitmq
* ci: logs from rabbitmq as json to console
* ci: tmp volume for rabbitmq
Needed since rootfs is now read-only
* ci: fix permissions on /var/lib/rabbitmq vol
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.
