Roles and performance schema (feature request?)

          Description

          performance_schema ignores roles. This is a feature request, but a new user would probably think this is a bug.

          1) performance_schema.threads has a ROLE column, but it's always NULL.
          2) When a user connects, a matching row is searched in performance_schema.setup_actors, including the ROLE column. However, the check is never re-done after connection, even if the user sets a role. In practice, a row with ROLE <> '%' will never match anything.

                Maybe I should explain the reason for this request.

                setup_actors lets me decide what threads are [not] instrumented, based on user/host. But I want to instrument the threads which perform some actions, and the best way to identify them is specifying their role.
