Restore rabbit.host and add an haproxy rabbit listener

To balance load over the rabbit cluster we want to route access
to it via haproxy.

This also helps workaround bug #856764 as an additional benefit.

This change sets rabbit.host to the ControlVirtualIP (to be used by
the elements) and adds an haproxy listener for the rabbit nodes.
