This plugin activates per-interval collection of various statistics based on the kernels cgroupv2 controllers during the build phase and dumps a json file ‘system_monitor.json’ with the collected statistics in the result dir

Currently dumped statistics include total maximum memory usage for the build, the process with maximum memory RSS and max swap usage

The plugin requires the use of systemd-nspawn as build container runner
