Add Bosun, scollector, OpenTSDB and HBase

I've bundled all of these services up in to one pull request, as ultimately I was interested in getting Bosun working. I've got this running locally, and I can confirm `scollector` works, pushes data into `bosun`, which is storing data in OpenTSDB via HBase. Phew. So all parts seem to work! Would like someone to have a look over this before I merge it though.
