Option to use YAML instead of JSON for OpenAPI definition of API

[antonroman]

Can we use YAML for the OpenAPI definition of our API?
As it is expected to be edited by humans and it is not going to be frequently serialized/de-serialized AFAIK, I would prefer to use YAML instead of JSON.
It looks much easier to edit, to me at least. I guess the swagger tool should work well with YAML as well as the validation tool.

Thanks in advance!
