• I have verified that new and existing unit tests pass locally with my changes
• I have not allowed coverage numbers to degenerate
• I have maintained at least 90% code coverage

How Has This Been Tested?

We are only updating least k8s version needed to run e2e, and hence not require any sanity tests
