AddDispatch increments the # of dispatched requests for flow control.

AddEpochAdvance notes an advance of the progress meter baseline for a given priority level.

AddReject increments the # of rejected requests for flow control.

AddRequestConcurrencyInUse adds the given delta to the gauge of concurrency in use by the currently executing requests of the given flowSchema and priorityLevel.

AddRequestsExecuting adds the given delta to the gauge of executing requests of the given flowSchema and priorityLevel.
