While SERVER-95522 is about exempting "process internal" tasks from the admission control policy, this ticket is about exempting "cluster internal" commands. For example in a replica set, the LogicalSessionCacheRefresh/Reap will send "update" commands to each connected mongod in the cluster. These operations which come from a "MongoDB Internal Client" connection should not consume a ticket because they are part of an expected internal operation and necessary for a healthy cluster.
