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

```console
deis/registry                    reduce_size         2bb393d9b63b        1 hours ago         379.7 MB
deis/registry                    latest              a8031e3ad8e1        2 days ago          501.3 MB
```

The idea is to use a script to install all the requirements to run the registry 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.
