Jenkins Cloud Builder

Motivation: The current build system works beautifully for producing images for Amazon. However, as Amazon adds more regions and as we add more build targets, the process of building the images has morphed into more of workflow. By migrating the build system to Jenkins, we'll have the ability to track the different builds, integrate testing, and allow for official derivative images to built from a single source.
