[Li0k]

I found a bug that:
After pick_compaction, compaction_status will hold the pending_task in memory. so if send_task rpc fail, the state of pending_task remains in memory and prevents subsequent compaction.

how to resolve this ?
I think that we need to cancel the pending_task status when send_task rpc fail to avoid the above , and i add some unit test for this case.
