deis 1.0.2 (new formula)

Deis recently reached a production ready 1.0 product. It will be nice to have the client utility in Homebrew.
Can this test be modified to do something more substantial than e.g. `--version` or `--help`? See `cmake.rb` for an example of an application formula with a good test and `tinyxml2.rb` for an example of a library formula with a good test. Thanks!
