Set up different API Stages for Jenkins instances
Set up different API stages that point to different jenkins instances (build vs. test).
Things to consider:
The map between, e.g. "build" as a stage going to URL: https://build.testeng.edx.org. Could be programmatic (i.e. build goes to build.testeng.edx.org, and we create the correct ELBs for that)
The spigot toggle code / job would need to know which gateway(s) to toggle (API stage variable)
