      Description

      The group assignment changes introduce new methods to the MasterObserver interface. This is a concern for things like Apache Phoenix. (See their IndexMasterObserver, etc.) We can handle this by using compatibility helpers that won't attempt to invoke the new APIs on MasterObservers that do not implement them.
