Setup a docker registry proxy to be independent of the hosting

[mgautierfr]

With the recent change on the dockerhub side (removing of Docker free team), we have decided to change the hosting of image to something else.

But instead of changing all our scripts, documentation, communication to point to our new hosting, we could setup a docker proxy (registry.kiwix.org) which point to our hosting (dockerhub for now, new hosting once we have changed) and make all our script/doc/com point to the proxy.

This way, when we want to change our hosting (now or later), we "only" have to change the proxy configuration.

@mgautierfr Sounds a good idea. You have a link to Linuxfr to share with the details?

It's a good idea but just to be clear Docker Hub is more than just a registry and offers features that are not part of the registry API such as anonymous tags listing etc
