ensureSynchronized(containers)	Promise<void>	Make sure all the tracked containers are synchronized. - No isDirty (non-readonly) containers - No extra clientId in quorum of any container that is not tracked and still opened. - i.e. no pending Join/Leave message. - No unresolved proposal (minSeqNum \>= lastProposalSeqNum) - lastSequenceNumber of all container is the same - clientSequenceNumberObserved is the same as clientSequenceNumber sent - this overlaps with !isDirty, but include task scheduler ops. - Trailing NoOp is tracked and don't count as pending ops.
pauseProcessing(containers)	Promise<void>	Pause all queue activities on the containers given, or all tracked containers Any containers given that is not tracked will be ignored.
processIncoming(containers)	Promise<void>	Pause all queue activities on all tracked containers, and resume only inbound to process ops until it is idle. All queues are left in the paused state after the function
