This change works around an issue in the rabbitmq-server version shipped with Ubuntu 20.04. Large emptyfiles limits in docker containers which run on hosts with low emptyfiles limits cause rabbitmq to break. It will use use 100% CPU of a single core when started, then time out (i.e. fail to start). An erlang process 'erl_child_setup' will continue to use 100% CPU even after rabbitmq failed to start (see docker-library/rabbitmq#545). The change adds a default emptyfiles limit to rabbitmq-server via /etc/default/rabbitmq-server, which is created in the Dockerfile before rabbitmq is installed. The default is generous: 65536. Additionally, the change ads a new container environment variable RABBITMQ_EMPTYFILES_LIMIT which, when set, will override the default above.
