🔌 Plugin: Keycloak

[serenamarie125]

Goal

This epic aims to develop a new Backstage UI plugin in the Janus repo.  This UI plugin should integrate Keycloak into Backstage to enable Keycloak user and group entities to be used in the standard Backstage catalog model.

What problem does this solve?

Although Backstage contains the functionality to connect to external identity providers to enable authentication and apply proper RBAC, there is no integration point with Keycloak authentication today.
