f03765814e Add some trace-level logging for /v1/agent/servers when writing 
This endpoint shouldn't be hit often, but this could be useful in
logs down the road.

37e7038a27 Fix config_parse_test to reflect that consul.addr does not exist. 
`consul.address` does, but not `consul.addr`.

a55395678f Fix tests for client.TestAgent_ServerConfig 
Add similar logic in Agent `serverConfig()` to set up the
`serverSerfAddr` the same as `serverHttpAddr` and `serverRpcAddr`.

ed30876186 Change the endpoint for /v1/agent/servers and fix tests. 
When an agent is running a server, the list of servers includes the
Raft peers.  When the agent is running a client (which is always the
case?), include a list of the servers found in the Client's RpcProxy.
Dedupe and provide a unique list back to the caller.

b9f230b7b2 Move client.DefaultConfig() to client/config.DefaultConfig() 
Resolves an import cycle in testing and is more appropriate because
the default should reside next to its struct definition.

bc86e897ed 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.

ce8c03d708 Advertise the server's RPC endpoint, not its HTTP endpoint. 
Rename c.serverRpcAddr to serverRpcAddr.  This will be broken out
into in additional set of services in a subsequent commit.

e6397da738 Centralize the creation of a consul/api.Config struct. 
While documented, the consul.timeout parameter wasn't ever set
except one-off in the Consul fingerprinter.

71dde1b584 Reconcile consul's address configuration section. 
There were conflicting directives previously, both consul.addr and
consul.address were required to achieve the desired behavior.  The
documentation said `consul.address` was the canonical name for the
parameter, so consolidate configuration parameters to `consul.address`.

092e07f334 Create a nomad/structs/config to break an import cycle. 
Flattening and normalizing the various Consul config structures and
services has led to an import cycle.  Break this by creating a new package
that is intended to be terminal in the import DAG.

0e1bdad2a0 Rename consul.ConsulConfig to consul.AgentConfig 
There were two `ConsulConfig` structs running around, one of them
needed to go away.  Rely on the package's path to provide context
for the type of AgentConfig.
