Decorators for expected exceptions in comomn/rpc are handled by
allowed_rpc_exception_modules config option and should not be needed
in engine.py

Refactor stack watching into a separate class

In later oslo.messaging patches, the Stack watch functionality must
be called from two separate places (the endpoint class and the service
class).  In order to do that and not result in needless code
duplication, break it into a separate class and so the object can
be passed around.
