Adds information on whether a specific project car read/write zstd compressed files in the project-info.json

Ben Couturier requested to merge add_zstd_info into master

This MR does not update the stacks, but changes the data exported to CVMFS by the GitLab CI. No need for the usual validations, this will not trigger a build

It updates the code that is invoked by the CI to generate the file /cvmfs/lhcb.cern.ch/lib/var/lib/softmetadata/projects-info.json, so that the data for a given version of a project becomes:

   "MOORE": {
        "v10r1": {
            "GAUDI": "v21r10p1",
            "LCG": "58e",
            "ROOT": "5.26.00cp1",
            "platforms": [
                "slc4_amd64_gcc34",
                "slc4_ia32_gcc34",
                "x86_64-slc5-gcc43-opt"
            ],
            "read_zstd": false,
            "write_zstd": false
        },

Other changes to be considered in separate MRs:

  • The code that maps from LCG version to ROOT version actually has to fetch data from https://lcgpackages.web.cern.ch/lcg/meta/, this should be reviewed in a later MR.
  • xrootd version information
  • upgrade of python for the CI tests (currently 3.8)
