This PR implements logic within sled-agent to clear mupdate overrides. Includes tests, database storage, and displayers.

This logic by itself does not introduce behavior changes, since the code to actually set this field is in #8456.

While working on #8572, we realized that we need to put in a condition
saying that if any zones can't be switched over to Artifact, we must not

about eligibility to be available in two spots: while updating the
mupdate override, and while doing these noop conversions.

In order to do that more easily, this PR builds up a decision tree by
sled.
