The cluster tests use the same image build that we use to publish release images. The tests were also written to use the
latesttag by default. However, we don't produce alatesttag when we publish release candidate images. This caused the tests to fail on the most recent release branch because it was trying to test a nonexistent image.This commit resolves the issue by reusing the existing
CONTROL_PLANE_VERSIONenvironment variable to compute the default tag in the cluster tests.You can test this change by temporarily creating a pre-release tag and running the tests.
