Use Provider to obtain LifecycleListeners
Instead of holding onto a singleton for a LifecycleListener, allow the
listener to be created on demand using a Provider.
Use explicit support of the HandlerRegistration type, enabling these
to always be cleared before any LifecycleListener is stopped. This way
registrations from plugins can always be cleared even if the list of
listeners to start didn't finish running to the end.
During stop only run those listeners that attempted to start. We
assume a listener is prepared to run its stop method as soon as its
start method begins execution. This means a start method that can fail
must use guards in its stop method to handle stopping after a partial
start failure.
