Description

Update OLM deployer to work with the current op structure.

Tested with OLM manifests from: stackabletech/openshift-certified-operators#20 which were generated from the Helm manifests in this branch.

🟢 Kuttl tests on OpenShift 4.17:

# Skip installing the secret op since it's been already installed by OLM
$ ./scripts/run-tests --test-suite openshift --skip-operator secret
...

LGTM! I ran the tests with the deployed bundle, but also with the operator deployed via stackablectl: all good!
