Create CI OpenShift cluster and run install test
With https://gitlab.com/gitlab-org/gl-openshift/gitlab-operator/-/issues/25 we now have scripts for creating OpenShift clusters. We should use these scripts to create a cluster for integration and functional testing of this project. This issue is scoped to creating a first "does it install" integration test that will run as part of our pipelines.
Acceptance criteria:
- OpenShift cluster is launched for CI
- Any connection secrets are stored in CI variables (maintainer will have to do this)
- A new functional test is added that installs the operator in the CI cluster and verifies it has installed without error. This should be a simple yes/no test for this issue, we can expand upon it.
