[MINOR UPDATE]: Fix Hadoop 3 impersonation test errors during CI runs
Description
The following changes are made to resolve the "IO Running in secure mode, but config doesn't have a keytab" errors currently plaguing the Hadoop 3 impersonation tests when (and only when) they run in the GitHub CI [1].
Ensure that MiniDFS is using simple auth in BaseTestImpersonation.
Shut down MiniDFS cluster in TestInboundImpersonation.selectChainedView
These changes are sufficient to fix what I believe is a racy test harness set up / clean up bug that at this time only presents itself in the GitHub CI, and even then only with recent GitHub Runner images.
I'm not sure why the CI didn't kick off, perhaps because I had the wrong merge target branch set initially. I'll try to push up an empty commit to see if that gets it going.
