> Wait queue uses first attempt start time for ordering. Since different AMs can submit
requests to llap daemon, if AMs are not clocks are not synchronization then this might lead
undesired ordering of requests in wait queue. It will be good to have current attempt start
time so that the difference between first attempt start time and current attempt start time
can be used for ordering.
