Addition of Crate Data

 Hi, as already discussed with @cpuguy83 - it would be nice to have the Crate Data Dockerfile in your official repository. 

For more information about crate, here are some links:

home: https://crate.io
github project: https://github.com/crate/crate
github project for dockerfile: https://github.com/crate/docker-crate

thx, bernd
