Make The Node Name Settable

[pnovotnak]

I think this might be a dupe or at least partial dupe of #73, but it's really crampin' my style, so I'd like to make sure you folks upstream know about it, because I cannot imagine I'm the only one.

My use case is; I'm trying to run an application inside of Kubernetes with a Rabbit broker. However, I need persistence. Since I cannot set the hostname via Kubernetes (reported, as issue 4825 I cannot run Rabbit in the cluster.

For reference: docker-library/rabbitmq#6

You can set node name. If that's not possible with Kubernetes, this sounds like a Kubernetes limitation to me.

Running two nodes on the same host is perfectly possible: change the part before the @. For example, some of our test suites use rabbit@hostname and hare@hostname.

Sorry for my ignorance! I had seen the RABBITMQ_NODENAME variable in the documentation and tried using it, but was not setting up my container correctly.
