Summary
On Enterprise Linux 9 (EL9) the system uses cgroups v2, and the supremm was only matching cgroups v1 paths. This caused cgroup memory-related graphs on XDMoD to be missing while they are scraped successfully with valid data samples. This PR adds support for the cgroups v2 path layout and detection so the supremm correctly matches against correct cgroups data index and reports memory metrics on EL9.
What I changed
1- explicit v1 path match.
2- explicit v2 path match.
3- fall back to anywhere /job_<job_id> path appears.
