With OCL GA'ing soon, we'll need a blocking path within our e2e test suite that must pass before a PR can be merged. Since e2e-gcp-op-techpreview is a non-blocking job, we should do both of the following:

1. Migrate the tests from e2e-gcp-op-techpreview into e2e-gcp-op. This can be done by moving the tests in the MCO repo from the test/e2e-techpreview folder to the test/e2e folder. There might be some minor cleanups such as fixing duplicate function names, etc. but it should be fairly straightforward to do.
2. Make e2e-gcp-op-techpreview a blocking job. A PR to the openshift/release repo to set optional: false for that job in both the 4.18 and 4.19 configs will be needed. This should be a pretty straightforward config change.
