Review comment:
minor : not sure if all task execution will always come from
`GobblinMultiTaskAttempt.java`, so can it use
`Long.toString(System.currentTimeMillis())` instead of "0" as default? Also do
we have to put `TASK_START_TIME_MILLIS_KEY` while beginning the task? can it
not be just any current time when it comes here if its configured? ( start time
would be helpful for other metrics though)
