setup.py includes tests directory in package data

[bwind]

Issue Summary

setup.py includes all packages (containing an init.py) using find_packages(). This is a problem because it will include the tests directory as a top level importable module in the local app, breaking our own tests that happen to live in a directory with the same name.

Steps to Reproduce

1. pip install python-http-client
2. ls /usr/local/lib/python3.7/site-packages/ and observe tests is there as a top level importable package
3. import tests from local app will import python-http-client's tests, not the app's tests

Either init.py should be excluded from the package data, or (rather) the entire tests directory.

Technical details:

• python-http-client 3.2.0+
• Python Version: 3.7
