Update uWSGI dependency version (#164)
Update uWSGI dependency version (#164)

Relates to feedback from [Clank Issue 63](https://github.com/iPlantCollaborativeOpenSource/clank/issues/63) where the uWSGI 2.0.9 on Ubuntu 16.04 encounters a compile on pip install.

This will require verification in the dev environment. A merge into dev can be verified using the QA regression tests, both API & QA.
