Many tests are still failing in our rolling CI builds that have been failing for longer than our ADO pipeline has been running them.

To facilitate maintaining current quality levels we must skip these known-to-fail tests until we get time to adequately fix them.

For each known-failing test, add code that will skip for the OS(s), for the python version(s) it is known to fail in only.

Once the Rolling-CI test runs green, ensure all new failures cause the build to fail completely.
