This commit does two things: it reports the status of the microservices
proxy in the `portRouteInfo`, so that if that's disabled we would
immediately know, and it also stop spawn the proxy `Application` in case
it's disabled. This wasn't the case before; previously we would be
spawing the proxy process even though it was "morally" disabled.
