`dapp-runner` doesn't detect/report network IP collissions

[shadeofblue]

misreports the specific service as running despite the fact that no commands had ever been executed in the container

to reproduce, launch the service on 192.168.0.1 -> this address is automatically assigned as the requestor's ...

e.g.

nodes:
  cache:
    payload: "cache"
    init:
      - ["/bin/bash", "-c", "redis-server --bind 0.0.0.0 --loglevel debug > /dev/null &"]
    http_proxy:
      ports:
        - "6379"
    network: "default"
    ip:
      - "192.168.0.1"

the providers can use addresses other than the first one on a given network but dapp-runner should still properly detect/report this issue
