WIP: machineset annotator

[michaelgugino]

Half-working pricing annotation controller.

We should use code-generation to incorporate the pricing similar to what the autoscaler does upstream, rather than attempt to use the pricing api (which is very problematic due to permissions, and region restrictions/networking).

Upstream cluster autoscaler downloads the pricing info for each provider, generates code with the pricing information, and that pricing information is built into the autoscaler binary. We could utilize the same here (ideally, make that logic more portable in the upstream autoscaler as well so we can just import the functionality).
