I know this is a huge change. The proxy still isn't very advanced, this just cleans it up and lays some framework down. Most functionality was moved out to a direct client. There's a proxy context to hold auth info and per-request caches. Better tempauth. I mean it's still not great, but it's better. Inklings of callback-based authentication. Account and container info fetching and caching. Change-Id: I2543040a5f9faed20e713eb24e2189801232b76e
