Refactor Process Stats and Bugfixes (#6344)
* test refactor process stats * Update util.py * bugfix * black formatting * add missing processes field to StatsTrackingTypes class * fix python checks and tests... * use psutil for calcilate cpu utilization on get_cpu_stats * black...black...black... * add cpu average * calculate statiscts for logger process * add P-ID for other processes in System.jsx * Apply suggestions from code review Co-authored-by: Nicolas Mowen <nickmowen213@gmail.com> * make page beautiful again :) --------- Co-authored-by: Nicolas Mowen <nickmowen213@gmail.com>
