Configure binding endpoint related environment variables

[thomschke]

In service mesh environment (Istio) the ingress traffic is passed through a sidecar-proxy. For this reason all application sockets have to bind to 127.0.0.1 (or 0.0.0.0) and NOT to status.podIP (see akka/akka-management#209).

Currently all related environment variables "_HOST" and "_BIND_HOST" are using status.podIP.
