Hello, please review this PR; it extend the OSContainer API in order to also
support the pids controller of cgroups.
I noticed that unlike the other controllers "cpu", "cpuset", "cpuacct",
"memory" on some older Linux distros (SLES 12.1, RHEL 7.1) the pids controller
might not be there (or not fully supported) so it was added as optional , see
the coding
if (!cg_infos[PIDS_IDX]._data_complete) {
log_debug(os, container)("Optional cgroup v1 pids subsystem not found");
// keep the other controller info, pids is optional
}
