Docker migrate to overlay2 from aufs script

Crazy that this is pretty much forced change without proper transition script

note. Based on https://www.sylvaincoudeville.fr/2019/12/docker-migrer-le-stockage-aufs-vers-overlay2/ NOT WORKING!!!! IF FOLLOWING THE ABOVE.. SOMEHOW THE CONTAINERS DO NOT RE-APPEAR!

The only way I found that is somewhat automated is the the docker-compose way..

Which is still not 100% and require manual fixing of stupid errors of the docker-compose tool (mainly things that ere not interpreted right, like dates & userIds that need to manually surrounded by quotes etc)
