Fix Debug in Container

- on Windows (possibly Mac as well), we can't use the ip of
  the Container to contact the gdbserver as this address
  may be hidden from the host behind a VM
- instead use the localhost port that the tcp/2345 is mapped
  to which the Docker machine etc.. forwards back
- fix this in ContainerLaunchConfigurationDelegate
