So, setuptools broke the installation setup, by removing a deprecated API that is still used by some of our dependencies (see pypa/setuptools#2017)
This PR fixes the Docker build by using pipstrap to pin pip/setuptools/wheels, like it is done in several critical places (certbot-auto, ...).
An issue in certbot is opened to fix more generally the problem in most recent versions of setuptools: certbot/certbot#7976
It rebuilt locally all dockers (certbot + dns plugins) for the three architectures, and all have passed.
This PR adds appropriate corrections to certbot dockerfile to work with the new layout (moving certbot python project in its own subdirectory).
This PR has been tested with success using the `build.sh` script on a fake v1.0 version of certbot published on my fork (https://github.com/adferrand/certbot/releases/tag/v1.0) instead of archives from `certbot/certbot`.
