Add upper constraints to glanceclient2.0.1

This will force pip install to use the upper-constraints.txt specified
version of pip modules. When you don't do this, you are out on the
bleeding edge and become unstable everytime some python library in the
world changes in a way that you don't expect.

The script is needed because it cleans up the conflicting entry that
corresponds to the client before applying it to source based
installation.
