The "aud" claim of the logout token is supposed to contain the client-id
of the client for which the token was issued. Our current implementation of
validating that claim is somewhat broken. We only allow to configure a single
value for the allowed client id. But we have different client-ids
accessing oCIS.
This completely removes the current validation of the `aud` claim until
we come up with a working solution. As we currently require a session id
to be present in the logout token the risk not validating the `aud`
claim is pretty low.

Use access token to lookup session id. The userinfo endpoint does
not return the session id. Also add some debug logging.

* Remove unused code from oidc module
* Use already existing Metadata type for jwks discovery
ocis-pkg/oidc already provides a type for the oidc metadata. Switch to
that instead of defining yet another custom type.
