Change python coveragerc file

[aphanse]

@estute @jzoldak @benpatterson
Changing the python coveragerc file to work when using different versions of the unit coverage and test subset job. For context, this file gets called by the unit coverage job in order to create the reports for coverage.py. Thus, the $JOB_NAME is the unit coverage job. This is done to make sure python unit tests pr job works on the various repositories.

If a jenkins worker runs one job, then sticks around and runs another one, is it possible that this we will get inaccurate results? We don't clean up workspaces after jobs end.

Another concern - for workers that can run concurrent jobs, IIRC the workspace folder name will append a numerical identifier to distinguish. workspace, workspace@2, workspace@3. I'm not sure if we considered that in the original lines that you're changing now.

1. No, we shouldn't get inaccurate results. The environment variables which are added by the unit coverage job would have changed.
2. The file is run by unit coverage which works on coverage worker which cannot do concurrent jobs as far as I know. The lines would likely not be able to handle having different workspace names, but since coverage worker doesn't support that anyway it should be fine.

Thanks for answering my ?s.
👍 for merging
please verify the coverage # after merging and make sure that it matches that calculated before the merge.
