Register two services each for clients and servers, http and rpc.
...
In order to give clients a fighting chance to talk to the right port,
differentiate RPC services from HTTP services by registering two
services with different tags. This yields
`rpc.nomad-server.service.consul` and
`http.nomad-server.service.consul` which is immensely more useful to
clients attempting to bootstrap their world.

Allow ports to be optional when adding servers
...
When updating a clients servers, as nomad does not use the gossip
protocol over a specified port for clients, it was required to specify
ports along with server addresses.
Now specifying ports are optional, and if unspecified the default `4647`
port is used, reflecting a notice back to the user.
