Currently, the OIDC auth provider is only documented/ supported with Keycloak, but it works with any OIDC-compliant IdPs. Write an article for customers to understand how this works with catalog ingesters and things to keep in mind if a custom resolver or transformer is needed. 

Things to include:

• Explain how catalog ingesters and auth providers work (completely separately), and how the resolver links the 2
• How to develop a custom auth provider to make sure the resolvers work and match on the correct identifier in the ingestor plugin
