Add new class for Logging API methods
Not all logapi "DriverBase" [1] methods are implemented in rpc "LoggingApiNotification" [2] Now above classes inherit from class 'LoggingApiBase' [1]cf0cc1f4f2/neutron/services/logapi/drivers/base.py (L27)
[2]cf0cc1f4f2/neutron/services/logapi/rpc/server.py (L102)
Closes-bug: #1960533 Change-Id: I9fbfa0f823bcdde60910b018ef2a8fdffaf3512c
