> Change Notes:
>  * Divide origin TablePermission into three classes GlobalPermission, NamespacePermission, TablePermission
>  * New UserPermission consists of a user name and a permission in one of [Global, Namespace, Table]Permission.
>  * Rename TableAuthManager to AuthManager(it is IA.P), and rename some methods for readability.
>  * Make PermissionCache thread safe, and the ListMultiMap is changed to Set.
>  * User cache and group cache in AuthManager is combined together.
>  * Wire proto is kept, BC should be under guarantee.
>  * Fix HBASE-21390.
