[keycloak-user] Backend to Backend Call

Actually this is not a use-case that we solve particularly well, but
passing the refresh token is not a great idea.

One option would be to increase the access token timeout, but that would
have side effects on all other use-cases. The best and most secure option
would be to have a one-time token that is passed to the asynchronous
service. This is not something we have support for directly though and it
would most likely not involve the IdP (Keycloak server) at all, but rather
be a signed JWT issued by the caller that can be used by the async service
for the callback.
