This MR converts the repository to
poetry instead of
tito for easier tracking of the dependencies and easier safe usage. The CI is also fixed and adapted. As an optimization, a custom CI Docker image is produced.
RPM creation will be added in a subsequent MR.
The repository can be used locally following the instruction in the developers' guide.
The CI is also fully working:
master): will appear in https://gitlab.cern.ch/cmsgemonline/gem-online-analysis/-/packages
