Merging dependencies into master - merged into high-level-commands in…

… last pull request. (#12)

* Installing the dependencies and file structure needed for high-level commands to actually put files into the cloud.

* Removed tests because i/o args changed quite a bit. Adding tests at the end.
* Made _mime_type function readable
* Added replica argument to upload_to_cloud script
* Changed default staging bucket to an environment variable.
* Removed scripting capability of upload_to_cloud.py
