Consolidate componentconfig code standards

**What this PR does / why we need it**:

This PR fixes a bunch of very small misalignments in ComponentConfig packages:
 - Add sane comments to all functions/variables in componentconfig `register.go` files
 - Make the `register.go` files of componentconfig pkgs follow the same pattern and not differ from each other like they do today.
 - Register the `openapi-gen` tag in all `doc.go` files where the pkg contains _external_ types.
 - Add the `groupName` tag where missing
 - Fix cases where `addKnownTypes` was registered twice in the `SchemeBuilder`
 - Add `Readme` and `OWNERS` files to `Godeps` directories if missing.
