Turns out that putting this in the main build definition starklark file
means that our users will also incur a dependency on the repo rule.
That's no bueno.
This reverts commit 78e443b4f6.
The source code is moved from src/python to
src/python/src. A setup.py is added at
src/python. The build_python.sh and
run_python.sh scripts are updated to build
and run the Python tests by building a
package and installing it in the developer's
Python 2.7 virtual environment.
