Deploy RabbitMQ on docker-001

Summary:
Define the available ports, so we can enable further protocols when needed.

Define a dedicated "restricted" IP, for use only for Nasqueron servers,
currently the public IP. In a follow-up change, when Drake network is ready,
we'll update that IP to 172.27.27.6.

Upstream image now uses /var/lib/rabbitmq instead of /data.

Nginx uses default config, but like Openfire, we proxy to the dedicated IP.

Test Plan:
Launch on docker-001:

• salt-call --local state.sls_id /etc/nginx/vhosts/rabbitmq/white-rabbit.conf roles/paas-docker/nginx
• salt-call --local state.apply roles/paas-docker/containers/rabbitmq
