      Description

      Currently master coprocessors can only function as observers. However, it would be useful in some cases, especially with "system" tables moving to be served by the master, for master coprocessors to be able to function as endpoints. These coprocessors would then have access to master facilities to be able to perform custom cluster coordination tasks, for example.

      One example application of this would be for security grant and revoke commands, where a master coprocessor could make use of the procedure mechanism to ensure that all regionservers acknowledge an update before returning success to the client.
