[tech debt] migrate operator-controller command handling to cobra

[grokspawn]

(clone of #1567 which applied to catalogd flag handling)

Maintenance/update of operator-controller flag handling would be greatly simplified by adopting https://github.com/spf13/cobra

Hello, I'd like to work on this. The first link isn't working, did you mean https://github.com/operator-framework/operator-controller/blob/main/cmd/operator-controller/main.go ?

@grokspawn , may I get some clarification so I can start working on the issue? Thank you

Hi @o-farag. You're correct that it's for operator-controller's flag handling, and I fudged the URL. I fixed it.

Awesome, I'll start working on this then if no one else has
