kops validate output yaml and json

[chrislovecnm]

Would be awseom if kops validate would output yaml and json. I will update the issue with a couple ideas on the format.

@chrislovecnm Are you thinking about something like kops validate cluster -o yaml, similar to the kubernetes get pod -o yaml?

[chrislovecnm]

@jatan28 exactly :) We would need an output format, but you get the idea. Would be helpful for programmatically using validate.

@chrislovecnm Do you have a design in mind for the output format? I saw that it is using print statements, is there an object that we can leverage for the structure of the output json/yaml. Once we finalize the design and approach, I can start working on it.

[chrislovecnm]

I don't, come up with something and let's iterate

@chrislovecnm What if we create a class for all the data that is getting rendered by this option, and then output it in yaml similar to kops edit cluster and json is fairly straightforward.

I'm not sure if it would make sense, but what if kops get cluster includes a status field, similar to kubectl get pods?
