* New module: Jenkins node management
* Fix sanity errors
* (Try to) fix mock import for Python 2.7
* Remove encoding from XML tostring in hopes of appeasing py27
Default encoding is probably always good enough.
* Turns out that encoding parameter was important for python3...
It's not super obvious how to resolve in a 2 + 3 compatible way,
so branch and omit encoding for 2.
* Implement review fixes and suggestions
