Implements: blueprint rabbitmq-dns-discovery Some useful things to note: 1. This uses a StatefulSet instead of a Deployment. The reason for this is that when RabbitMQ uses DNS for peer discovery, the first thing it does when trying to join a node is attempt a reverse-dns lookup. This reverse lookup works when using a StatefulSet, but not a Deployment. 2. The RabbitMQ configuration was updated to use the new sysctl-style format. It seems that the new format is required to configure the new autoclustering features. Additionally, I found that this generate much clearer error messages than the straight erlang format. 3. I removed the `is-node-properly-clustered` test in the liveness and readiness probes. This probe isn't directly supported in 3.7.0, and it wasn't clear that a clustering check was appropriate for each node. Change-Id: Ieefbb2205bd77fbac04abcd051fb06fce62e8d97
