Move unofficial testing images to https://hub.docker.com/u/toxdocker

@sashimi3 would you be willing to move https://hub.docker.com/r/ksdn117/tcp-udp-test to the toxdocker org?

[dcrosta]

Moving it will mean something like opening a PR here to create a directory in https://github.com/tox-dev/tox-docker/tree/master/docker with the Dockerfile and any support files needed

@sashimi3 Just wanted to ping on this again. I'm happy enough to do the work, but would love to have your permission, as you did create the image in question...

Can we expect another image if @sashimi3 does not update it?

This image is now too old to be used with modern Docker versions.
