this is just a workaround to get pylint to stop complaining? we can probably
remove this and cloud_storage_wrapper.py and just fix our pylint invocation

This was intended as a way to make the import sections at the top of
fetch_build.py and fetch_build_test.py look nicer; otherwise I think I'd have to
modify sys.path at the top of those files.

Doing it this way, mock can be imported in all of the tests in this directory
without having to add a statement modifying sys.path at the top of all of the
test files.

(I'm not sure if this is the best way to do this though.)

Stuff will either be run with a proper PYTHONPATH, and if it's not you should
look at add_build_paths() in
https://chromium.googlesource.com/chromium/tools/build/+/master/scripts/tools....
See it in action in

Hey, I didn't really understand what you're suggesting I do here. I don't think
that the PYTHONPATH is set up to include telemetry and pymock when the bisect
script is run on the bisect bots, although I'm not fully sure.

Are you suggesting that I should change something somewhere else and then assume
that the python path includes pymock and telemetry here?
