Added new python profiler for performance testing

[AsakerMohd]

Description of changes:

Added a new profiler.py script that uses psutils to get per process info such as Network Bytes Sent/Received, CPU, Resident Memory (Phyical RAM used), virtual memory and the peak number of threads. Updated the persisters as well to read the new data and populate summary.txt and results.csv as expected. Below is an example from a test run.

Also added a bunch of TODO comments to clean up old JFR logic that is no longer required here and to keep this PR changes to a minimum.
