Use operatorCI to provision a cluster for tests
Current tests use an existing dev OKD4 cluster. This will stop working if cluster is removed or re-provisioned.
@efokas's OperatorCI should allow to provision a cluster on the fly.
Note that a dev should still be able to quickly run the tests against their dev cluster, so make sure the e2e tests can be also run by just running a script in an existing environment.
It looks like other things are necessary to run the tests (see CI secret variables), these requirements need to be documented in the README
This is important because if the secrets/cluster are not functional anymore, CI will fail and any work on this project will be blocked.
