> 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.
