[keycloak-user] Unable to create keycloak admin client instance: class loader issue

[Marko Strukelj]

There should be a better way to access admin services within the same
container than by trying to do HTTP calls to Admin REST API.

Inside your custom listener you have access to a KeycloakSession, and
through it to all the system components you may wish for - you should
definitely use these rather than the roundabout way via DNS + HTTP +
Authentication + REST serialization / deserialization.
