Subject: [RFC PATCH v7 0/3] scheduler: Add scheduler overview

This patch series updates the scheduler documentation to add more topics
wrt to scheduler overview. New sections are added to provide a brief
overview of the kernel structs used by the scheduler, scheduler invocation,
context switch and Capacity Aware Scheduling. Previous version of
the patch was reviewed at:
https://lore.kernel.org/lkml/20200527084421.4673-1-John.Mathew@unikie.com/

version 7:
 -Fix overview description
 -Removed rst headers
 -Removed kernel-doc for struct rq and meged it as struct
  member comments

version 6:
 -Fix typos.

version 5:
 -Fix description error on CAS

version 4:
 -Added section on Capacity-Aware Scheduling
 -Reworded CFS recently added features.
 -Removed vruntime description from scheduler structs
 -Added description of idle and stopper sched classses

version 3:
 -Fix spelling, spacing and typo errors.

version 2:
- Remove :c:func: directive as it was redundant
- Limit document width (line symbol count) to 75
- Replace dot file with ASCII art
- Describe prepare_task_switch(), ASID use, 
  kernel/user transtion, MIPS FPU affinity correctly
- Add missing references to files
- Removed internal APIs from scheduler API reference
- Described rq struct member as kernel-doc comments
- Replaced CFS history with CFS current status
- Added documentation for sched_class fields
- Refined explanation of context swtich functionality
- Replace CFS history with recent changes
- Added kernel-doc comments for struct rq
