-------------------------------------------------------------

* Add a check on target user/group whether he is a superuser or a user in supergroup or neither.
* Add a new test: {{TestRpcAccessChecks#testGrantRevokeDeniedOnSuperUsersGroups}} which includes group permission test cases.
* Change visibility of {{TestingGroups}} to _public_ for test, otherwise, it can't be initialized in AccessChecker.

> Superusers are {{hbase.superuser}} listed in configuration and plus the one who start master process, these two may be overlap.
> A superuser must be a global admin, but a global admin may not be a superuser, possibly granted afterwards.
> For now, an non-su global admin with a Global.ADMIN permission can grant or revoke any superuser's permission, accidentally or deliberately.
> The purpose of this issue is to ban this action.
