            Phase 1 plan:

            • Add sending donors server version to jointer
            • Add finding out joiners server version
            • Add both to error log
            • Check donor's and joiners major versions
            • If major version is different (e.g. 10.7 vs 10.8) then
              • Reject SST request (both mariabackup and rsync) with clear error message
            • else
              • continue
