Harbor instance migration
Options to discuss :
- setting up a new harbor instance on the mim-libre.fr domain as https://hub.mim-libre.fr
- define the location of this instance (Scaleway? On premise on OpenNebula cluster ?)
- iso version of the instance currently in place on https://hub.eole.education (Version v2.7.1-6015b3ef)
- populating the instance with GitLab MIM Libre CI tools
