Now, when the user logs in and the connection becomes authenticated, the processing loop of the connection is switched to the scheduling group that corresponds to the service level assigned to the logged in user. The scheduling group is also updated when the service level assigned to this user changes. Starting from this commit, the scheduling groups managed by the service level controller are actually being used by user workload.
