FLUSH USER_RESOURCES
Resets all per-hour user resource indicators to zero.
This operation requires the FLUSH_USER_RESOURCES or RELOAD privilege.
Resetting resource indicators enables clients that have reached their hourly
connection, query, or update limits to resume activity immediately.
FLUSH USER_RESOURCES does not apply to the limit on maximum simultaneous
connections that is controlled by the max_user_connections system variable.
