[Hawtio] How to integrate Keycloak in Hawtio as a Fabric profile ?

Issue

When we create a profile to integrate keycloak with a Fuse Fabric in order to secure the Hawtio administration console.
A system property expecting one of the profile json resources (keycloak-hawtio-client.json) to be deployed in the ${karaf.base}/etc:

System Properties : 
      hawtio.realm = keycloak
      hawtio.rolePrincipalClasses =     org.keycloak.adapters.jaas.RolePrincipal,
        org.apache.karaf.jaas.boot.principal.RolePrincipal
      hawtio.keycloakEnabled = true
      hawtio.keycloakClientConfig = ${karaf.base}/etc/keycloak-hawtio-client.json

If we change this property using fabric URL Handler, it doesn't work:

hawtio.keycloakClientConfig = profile:keycloak-hawtio-client.json
