Description

Issue:
There is only one interface for RPC currently. The problem is that in a multi DC setup with federation we have to specify public IP's. This is a bad tradeoff for intra-region scaling of of nomad clients in that we would have to punch security group rules for each new nomad client added to a DC e.g. we should be using private ips for RPC intra-region.

Proposal:
Per discussion on IRC with diptanu add "wan_advertise" for cross region federation and allow "rpc" to be used for intra region rpc.
