Move package client/consul/sync to command/agent/consul.
This has been done to allow the Server and Client to reuse the same
Syncer because the Agent may be running Client, Server, or both
simultaneously and we only want one Syncer object alive in the agent.

Rename Syncer.SetServiceIdentifier to SetServiceRegPrefix()
This attribute isn't actually an identifier because it can represent
a collection of services.  Rename `serviceIdentifier` to
`serviceRegPrefix which more accurately conveys the intention of this
Syncer attribute.

While here, also rename `SetServiceIdentifier()` to `SetServiceRegPrefix()`
and `GenerateServiceIdentifier()` to `GenerateServicePrefix()`.

Change the API signature of Syncer.SyncServices().
SyncServices() immediately attempts to sync whatever information
the process has with Consul.  Previously this method would take an
argument of the exclusive list of services that should exist,
however this is not condusive to having a Nomad Client and Nomad
Server share the same consul.Syncer.

Change the signature of the PeriodicCallback to return an error
I *KNEW* I should have done this when I wrote it, but didn't want to
go back and audit the handlers to include the appropriate return
handling, but now that the code is taking shape, make this change.

Change client/consul.NewSyncer() to accept a shutdown channel
In addition to the API changing, consul.Syncer can now be signaled
to shutdown via the Shutdown() method, which will call the Run()'ing
sync task to exit gracefully.

Rename rpcproxy.UpdateFromNodeUpdateResponse to RefreshServerLists
While breaking the API within this PR, break out the individual
arguments to RefreshServerLists.  The servers parameter is reusing
`structs.NodeServerInfo` for the time being, but this can be revisited
if the needs of the strucutre diverge in the future.

Make the locking protocol more explicit in client.NewClient
With an over abundance of caution, preevnt future copy/pasta by
using the right locks when bootstrapping a Client.  Strictly speaking
this is not necessary, but it makes explicit the locking semantics
and guards against future concurrent or parallel initialization.

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.

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.
