Handle of the situation of failover
Just like the normal tasks, the speculative task is executed in parallel with the original one and share the same failover and restart strategy.
The original long tail task and speculative tasks can still retry with failure on their own track.
But I think it should not be restarted globally when the speculation execution failover count reach the max-retry-counts.
