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.

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.
