Since this command is part of the official distribution and even
required for tests, let's move this up to the main cmd's.

1. Allocate either a IPv4 and/or IPv6 Port Binding (HostIP, HostPort, ContainerIP,
ContainerPort) based on the input and system parameters
2. Update the userland proxy as well as dummy proxy (inside port mapper) to
specifically listen on either the IPv4 or IPv6 network

This simplifies how we build it in docker/docker as no vendoring needed,
and this does program not use any logrus features.

Rather than re-execing docker as the proxy, create a new command docker-proxy
that is much smaller to save memory in the case where there are a lot of
procies being created. Also allows the proxy to be replaced, for example
in Docker for Mac we have a proxy that proxies to osx instead of locally.
This is the vendoring pull for https://github.com/docker/docker/pull/23312
