purge rails
a new branch purge_rails has been created.
Commits have started to remove rails references (mainly docker-compose file and repository).
There's still some references for which I cannot say if they are still needed.
- commit : does this script still usefull ?
- django/docs/installation.rst : cf Database/warnings.
- all migrations tools.
- django/allgo/main/urls.py : some legagy links
- django/allgo/main/view.py : get_rails_webapp_metadata (and its uses related to imported apps.
- django/allgo/main/models.py : WebappVersion states "IMPORT".
