> There is a raise condition in request aborting process.
> Imagine, we have a request with couple of stages/tasks and one task is in IN_PROGRESS state. Then let's try to abort the request.
> Crucial steps of request aborting are:
>  # Get all not completed tasks for the request.
>  # Get QUEUED and IN_PROGRESS tasks from #1 and send cancel commands to the agents (we've sent cancel command for our task).
>  # Get tasks in HOLDING_STATES (HOLDING_FAILED etc.) from #1 and try to abort them.
>  # Get all tasks form stages which are not in COMPLETED state for the request.
>  # Get tasks from #4 which are in PENDING, QUEUED, IN_PROGRESS states and abort them.
> But if the server receive response from the agent for cancel command (sent in #2), then task will be transitioned from IN_PROGRESS to HOLDING_FAILED state. That's ok if it happen before step #2 (it will be aborted because has HOLDING_FAILED state) or after step #5 (it had IN_PROGRESS state and was aborted; update from the agent won't change state to HOLDING_FAILED, because we handle this case).
> But if we receive response from the agent between steps #3 and #5, then task will not be aborted and we will get a task with HOLDING_FAILED state after abort operation completion.
