cli: show CPU utilization (EMA); load-averages only when verbose

* add "SYS CPU(%)" column replacing "LOAD AVERAGE"
  - show "LOAD AVERAGE" when '--verbose'
* show "THROTTLED(%)" column iff any node reports non-zero cgroup v2 value
* update 'ais show cluster' help
* 'ais performance' - adding extended comment, leaving it intact for now
-----
* up modules to pick up new `apc.MemCPUInfo`
* part eight, prev. commit: 074554a
