0.0.7

Version 0.0.7 is the seventh Alpha-quality release of the service catalog. Below are some highlights from this release:

• We've made quite a few modifications to our data types, in preparation for the backward compatibility in the upcoming 0.1.0. Here are some of the PRs that made such changes: #862, #861, #859, #846, #843, #839
• We've made the controller be multi-node aware. When multiple controller pods start up, they all elect a single leader
• We've added infrastructural support for admission controllers to our API server. We've also added an initial admission controller in this release. We plan on expanding the scope of our admission controllers in future releases
