Bug Description

when re-balancing queues across agents, we blindly kill all existing listeners and then recreate the appropriate new set of listeners. it's entirely possible that some of the existing listeners will be consumed by current agent so we should be smarter when deciding what to kill

    retain existing listeners on refresh

    there is an overhead to killing and recreating listeners. this patch
    keeps the pipeline listeners we already have after rebalancing
    rather than blindly killing and recreating all of them.
