Gian Merlino 7557eb2800 CliPeon: Fix deadlock on startup by eagerly creating ExecutorLifecycle, ChatHandlerResource.
See stack traces here, from current master: https://gist.github.com/gianm/bd9a66c826995f97fc8f

1. The thread "qtp925672150-62" holds the lock on InternalInjectorCreator.class,
   used by Scopes.SINGLETON, and wants the lock on "handlers" in Lifecycle.addMaybeStartHandler
   called by DiscoveryModule.getServiceAnnouncer.
2. The main thread holds the lock on "handlers" in Lifecycle.addMaybeStartHandler, which it
   took because it's trying to add the ExecutorLifecycle to the lifecycle. main is trying
   to get the InternalInjectorCreator.class lock because it's running ExecutorLifecycle.start,
   which does some Jackson deserialization, and Jackson needs that lock in order to inject
   stuff into the Task it's deserializing.

This patch eagerly instantiates ChatHandlerResource (which I believe is what's trying to
create the ServiceAnnouncer in the qtp925672150-62 jetty thread) and the ExecutorLifecycle.
