[wip] Package deploy

Pull a file and explode it.

added some scripts for testing on vagrant box.

after booting up the vagrant box:
- `./install.sh` builds and installs the gem
- `./deploy.sh` runs the serverside deploy command with some stubbed values

## TODO

- [x] accept `--archive <url>` as Archive strategy
- [x] accept `--git <repo url>` as Git strategy
