Makes dev_setup.py script more portable

[zooba]

This will avoid problems where pip on PATH does not map to the version of Python that the script was started with.

I believe the exec_command function is now unused, but didn't want to just delete it. LMK if you want it gone and I'll take it out.

Thanks @zooba :). This was highly inspired by CLI, so they have the same issue (if you feel like PR it ;))

Yes, you can get rid of of exec_command if you have time. Thanks!
