> When calling {{dfsadmin -refreshCallQueue}} to update CallQueue instance, {{maxQueueSize}}
should also be updated.
> In case of changing CallQueue instance to FairCallQueue, the length of each queue in
FairCallQueue would be 1/priorityLevels of original length of DefaultCallQueue. So it would
be helpful for us to set the length of callqueue to a proper value.
