Title: feat(controller): image without development libraries to reduce the size.

```console
deis/controller reduce_size 5c6a6671dbb8 38 hours ago 335.6 MB
deis/controller latest 4001aac82196 40 hours ago 485.2 MB
```

The idea is to use a script to install all the requirements to run the controller and to remove all the development packages once the process finish. Running this script from the Dockerfile only one layer is created in which is possible to "release" disk space.
