In case there was an error during ApplyDeployment, the deployment would be nil, the controller would panic never to recover again.

@stlaz: This pull request references Bugzilla bug 1874713, which is invalid:

  • expected the bug to target the "4.6.0" release, but it targets "---" instead

Comment /bugzilla refresh to re-evaluate validity if changes to the Bugzilla bug are made, or edit the title of this pull request to link to a different bug.

why we are not using the generic workload controller for this deployment?

The generic controller is used to deploy the openshift-apiserver and the new oauth-apiserver

We don't use it because it only came after we started using the current logic. I bet there are side effects that would need to be solved (setting the operand version, for example, there might be more).

It's (probably) not impossible to use the generic workload controller, I just wanted to have this fixed fast.

@stlaz sounds like a tech debt Jira or bugzilla (your choice) :-) not urgent.
