* primitive implementation to demonstrate how it could work, still to be considered WIP at best * add new dependency: MicahParks/jwkset and MicahParks/keyfunc to retrieve the JWK set from KeyCloak to verify the signature of the JWTs sent as part of Bearer authentication in the /auth API * (minor) opencloud/.../service.go: clean up a logging statement that was introduced earlier to hunt down why the auth-api service was not being started
