URL: https://github.com/apache/spark/pull/29777
### What changes were proposed in this pull request?
With a long-running application in kerberized mode, the AMEndpiont handles
the token updating message wrong, which is a OneWayMessage that should be
handled in the `receive` function.

bugfix, without a proper token refresher, the long-running apps are going to
fail potentially in kerberized cluster
