Public bug reported:
This bug is to do some cleanup refactoring of the *aaS and L3 agent
interactions. It has several goals:
1) Switch from the L3EventObservers to the CallbacksManager mechanism for all
*aaS agents.
2) Remove/reduce the dependency of *aaS agents on the L3 agent
3) Eliminate the AdvancedService base class
4) Eliminate the *(now) unused advanced_service.py and event_observer.py
modules.
This will reduce from having two separate mechanisms to manage callbacks
from the L3 agent to the *aaS agents and their device drivers. (#1, #4)
It also simplifies the code. Instead of the classes, like VPNService,
from handling callbacks, forwarding calls to L3 agent to get router info
(removed in previous refactoring), maintaining another copy of L3 agent
and config settings( #2), and loading device drivers, the classes can
focus just on driver loading. Will no longer need a class hierarchy for
this as well (#3)
