Having multiple project discussions with ivan.kochin@mongodb.com  It was identified that we may not need generate-tsan-metric anymore. If we can migrating its functionality into run.py. which knows which python test produces a warning we can remove the generate-tsan-metric  and unit-test-tsan. 

Currently the unit-test-tsan sets an export to set the tsan log to the specific python test file it is running. Furthermore the generate-tsan-metric would read in the tsan log and provide a summary of the TSAN warning to it's respective python test file. If we can migrate this behaviour to run.py we can eliminate both evergreen tasks

Definition of Done
Migrate functionality of generating tsan metrics + unit test tsan work into run.py
