[SPARK-12101][CORE] Fix thread pools that cannot cache tasks in Worker and
AppClient
`SynchronousQueue` cannot cache any task. This issue is similar to #9978.
It's an easy fix. Just use the fixed `ThreadUtils.newDaemonCachedThreadPool`.
Author: Shixiong Zhu <[email protected]>
Closes #10108 from zsxwing/fix-threadpool.
