Controller Node should also have SSO authentication integrated

Feature Overview

Cu wanted to have integration with SSO as we have RH-SSO integration with Automation Hub.

Background, and strategic fit

Cu is having OpenID(https://github.com/pulp/pulpcore/blob/main/docs/authentication/keycloak.rst) connect for authentication in Private Automation Hub similarly they wanted to have the same authentication method for all the Automation Platform components. So they opened a case for having OpenId integrated with Controller Node same as PAH.

As the long-term goal is to fully integrate Controller with SSO cu have requested to have SSO integration with Controller.
