Major Description
ListenerManager should initialize all the listeners while initializing the listener manager, and starting of the ListenerManager should start the listeners.
Further, for synapse requirements we need to get rid of the shutdown hook and there has to be an option to not to set the shutdown hook while starting the listener manager.
this is required in the 1.5 release because synapse 1.3 is going to depend on the 1.5 release of axis2.
