Don't unregister failing post-exec callbacks automatically...

Don't unregister failing post-exec callbacks automatically Instead, print a message regarding the failure, pointing to new `disable_failing_post_execute` trait for skipping failing callbacks. When this flag is False (the default), failing callbacks will continue to be called. When True, behavior is unchanged from previous, where callbacks are only allowed to fail once.

      """These kinds of tests are less than ideal, but at least they run.

      This was an old test that was being run interactively in the top-level tests/

      directory, which we are removing.  For now putting this here ensures at least

      we do run the test, though ultimately this functionality should all be tested

      with better-isolated tests that don't rely on the global instance in iptest.
