Hi folks!

IIUC catbost's info.cpp supports only cgroups v1, and it would be great if you could extend the support to v2 as well.
XGBoost is doing a similar thing in dmlc/xgboost#9622

From a quick peek in https://github.com/catboost/catboost/blob/master/util/system/info.cpp#L52 it seems that only the old format is recognized.

Thanks in advance!
