The MCO's registry utilities was using the CC CR to fetch the proxy configuration and directly pass it to the container-libs image library (the old one, not the new mono-repo). Due to known limitations of the old containers/images libs and that the OS Image Stream logic used to live in the operator and not in the MCC, that recently gained the proxy env-vars, we handled the proxy in best-effort. There's already a fix in container-libs that allows us passing all the needed information to the library without the need of the env-vars (useful for scenarios that don't have them, like the operator), but the fix cannot be consumed till we migrate to container-libs from container/images. This change basically paws the way for the future migration while assuming that in the new current scenario with everything running in pods/containers/scripts that have the env-vars properly set, by ignoring the user given proxy settings if the configuration has NO_PROXY or different proxies for HTTP and HTTPS, delegating the proxy configuration to the underlaying container/images that will pick them from the env-vars.

- How to verify it
TBD
- Description for the changelog
Proxy configuration now falls back to system environment variables (HTTP_PROXY, HTTPS_PROXY, NO_PROXY) instead of only using the ControllerConfig proxy, fixing cases where NO_PROXY was ignored.
Summary by CodeRabbit
NO_PROXYvalues are recognized and included in proxy status information.
