Add support for local proxies

[charleskorn]

Once moby/libnetwork#2348 is merged and released, adding support for this on Linux should be straightforward.

Thanks for the feedback @pameck, this seems like something that batect should take care of for you.

On Mac it looks pretty straightforward: if the proxy refers to localhost or 127.0.0.1, use host.docker.internal on Docker 18.03+ or the now-deprecated docker.for.mac.localhost on Docker 17.06+.

On Linux, it's not quite that simple. docker/for-linux#264 talks about adding support for host.docker.internal to Linux hosts, but that hasn't been implemented. I'm sure there's a way to do it though, I'll do some digging.

Support for this on OS X has been added and will be included in 0.16.

Supporting this on Linux is way more involved, so I'm not going to add it right now.

Thanks again for the feedback @pameck!

With docker/for-linux#264 (comment), this is now unblocked for Linux 🎉
