STORM-1693: Do not cancel the task after stats are rendered
Fresher task is cancelled right after 3 seconds when executor heartbeat is
sent. getValueAndReset can rotate the buckets but it is not time bound. Metric
tick is in same queue as the input tuples from spout. If processing input
tuples is slow, it may take much more to generate metrics and call
getValueAndReset and thus `System.currentTimeMillis() - _bucketStart` is more
than 10 minutes.
