@pierDipi I switched the base branch to 1.15, since I realized the downgrade tests will no longer work for 1.14 -> 1.15 (as there are no deployments to remove anymore)

[Cali0707]

[knative-prow]

@Cali0707: The following test failed, say /retest to rerun all failed tests or /retest-required to rerun all mandatory failed tests:
