* keycloak_quarkus_http_relative_path var now populate http-relative-path config [breaking change]
* http-relative-path defaults to / [breaking change]
* enable configuration of hostname-url and hostname-admin-url
The documentation states that the path is relative to the /conf directory, which is true. So if one changes the contents of this file it would have no effect because the path would be non-existent. To make things worse, there would be no obvious error stating this and the configuration would be loaded from the defaults.
