* 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
