Add support for non replica actions to AsyncRequestFutureImpl.isActionComplete

The current isActionComplete method we have in AsyncRequestFutureImpl is only designed to support replica actions, it would be useful to have isActionComplete support non replica actions that could be reused for HBASE-27781 / #6144 and in other paths where non replica actions are being handled. 

Since isActionComplete currently only has one caller we can move the replica action check to the caller method instead of having the check be inside isActionComplete.
