Modify tests to require 100% subtest success, fix tempest

This is required to better align with functest, since that will handle overall
success/failure status. Also if a subestest failed, there were expected failures
that could seem like they pass making the overall success % look the same, which
would make the test look fine, even thought it failed.

Some tests check things that are known not to work. Disable these until they are
fixed upstream.

Also remove the success_criteria field from the config. Fail the test if any
subtest fails. This has the added benefit that it fixes the tempest suite, which
was still trying to read the value of `succes_criteria` that had been renamed to
`success_criteria`.
