[jira] [Created] (ARROW-10185) Add FinishAsync to TaskGroup

Weston Pace created ARROW-10185:
-----------------------------------

             Summary: Add FinishAsync to TaskGroup
                 Key: ARROW-10185
                 URL: https://issues.apache.org/jira/browse/ARROW-10185
             Project: Apache Arrow
          Issue Type: Sub-task
            Reporter: Weston Pace


As an alternative to Finish, FinishAsync will return a future immediately.  This can then be added to a parent task group, allowing for nested task groups.  Since the future is returned immediately, the child task group is not occupying a thread on the thread pool and there is no concern for thread starvation.
