Router: Fix persistent connection handling.

* Ensure `notifyContact` discards the response body. If the body is
  closed but not consumed, the underlying TCP connection will not be
  reused.
* Add an `IdleConns` option for controlling the maximum number of idle
  connections per host.
Add basic routing tests.
Add `GCMPingConfig.IdleConns`.

Remove ad-hoc HTTP client from `GetAWSPublicHostname()`.
Add socket count metrics.
Add `idle_conns` to the sample config.
Update mock stats calls in broadcast router test.
Add go cover check

Check to see if go cover is installed, prompt user if it is not.

Fix persistent connection handling in the router
Add balancers.

* Add a `Balancer` interface and `{Etcd, Static, No}Balancer`.
* Enable client redirects. `Worker.Hello()` returns a 302 if a peer is
  available, or a 429 if the cluster is full.
* Clean up etcd-related log messages.
