Check if plugin supports starting rpc listeners

Browse Source 
When neutron starts an rpc worker, it checks if the plugin has the method
"start_rpc_listeners".  Since most plugins inherit from a base class, and
that base class implements the start_rpc_listeners method and raises
NotImplementedError, the rpc worker will attempt to call that method.
It should just catch the NotImplementedError and continue on.
