Deploy: host statics from tigris buckets

[alichay]

Change Summary

What and Why: This makes fly deploy support deploying static files to tigris buckets instead of using a web server integrated in the machine's init process. This makes everything a little more efficient, allows serving static files when machines are stopped, and paves the way for further improvements to statics. :)

How: When deploying, if the app has static files defined, it will use (or create) a tigris bucket named after the app. Files are uploaded to this bucket, and a couple versions of file history are kept.
