      4.12 tech-preview jobs are suffering:

      with runs like this failing:

      Version-Release number of selected component (if applicable):

      4.12 tech-preview jobs are impacted.

      How reproducible:

      100% for some job flavors, per the search CI output above.

      Steps to Reproduce:

      1. Look at test results for any of the impacted job flavors.

      Actual results:

      Lots of NoKindMatchError events for v1 InsightsDataGather (it's only v1alpha1).

      Expected results:

      Passing test-cases.

      Additional info:

      The problematic REST-mapping client was removed from 4.13/dev as part of origin#27596.
