Add new task tracepoints
Created by: derkling
Task's utilization and load signals has been historically tracked using a sched_load_avg_task tracepoints. In more recent kernels instead we use a different set of more generic tracepoints as well as other tracepoints can be added to trace feature specific behaviours.
This series extends the TaskAnalysis API to be more generic by supporting a different set of utilization/load related tracepoints.
