VOL-2224 Event Filter Mechanism

         This commit contains the inital changes required for the event
         filtering so that when the protos get merged the rw and ro core
         could be built without compilation errors

         Note: This patchset and the patchset for voltha-protos needs to be merged
               as close to as possible otherwise there will be compilation errors
