> We are slowly getting to the point were our ability to improve Whirr will be limited by the cluster spec format. I'm opening this issue so that we can start to think about a new format that it's going to be more flexible. 
> Some of the characteristics of the new format should be:
> * low verbosity and easily editable using standard text editors. (e.g yaml)
> * easy to parse using existing libraries (e.g. snakeyaml) 
> * should allow values to be overridden as CLI parameters (e.g yaml liniarization - elasticsearch is doing this).
