Add support for static service lifecycle listeners .

Add support to AbstractService that allow callers to register listeners for all instances. The existing listener interface could be used. This allows management tools to hook into the events.

The static listeners would be invoked for all state changes except creation (base class shouldn't be handing out references to itself at this point).

These static events could all be async, pushed through a shared ConcurrentLinkedQueue; failures logged at warn and the rest of the listeners invoked.
