Additional property _transform is not allowed

[black-snow]

I'm just starting with kong and I pulled a kong.yaml from the docs that should be fine:

_format_version: "2.1"
_transform: true

services:
- name: my-service
  url: https://example.com
  plugins:
  - name: key-auth
  routes:
  - name: my-route
    paths:
    - /

consumers:
- username: my-user
  keyauth_credentials:
  - key: my-key

But when I deck validate this thing I end up with:

Error: reading file: validating file content: 1 errors occurred:
        (root): Additional property _transform is not allowed

Shouldn't the declarative docs match what deck is capable of? Or is there some other issue?

P.S.: I also stumbled upon Error: reading state file: stat kong.yaml: no such file or directory because I named it kong.yml instead ... I'd open a PR to allow both if my go skill weren't about -1. ;)

Same issue as #510, continuing discussion there.

The state file name I don't think you can easily address because of the way our arg parser and file readers work--you could set an additional default, but since we allow multiple state files I believe that will make us attempt to read both rather than one or the other, and likely fail because only one is present.
