processing_settings missing from site and siteSetup definitions

[daveaglick]

I'm in the process of creating a .NET client for the API and am using the Open API specification as a guide along with the API docs. This is probably the first of several issues I'll open as I find discrepancies between the Open API specification, the API docs, and what I see on the wire. I'm happy to tackle some of these as PRs as well, but want to get them in as issues first.

Both the API docs and the wire data contain a payload for a processing_settings property in the site and siteSetup objects;

"processing_settings": {
    "css": {
      "bundle": true,
      "minify": true
    },
    "js": {
      "bundle": true,
      "minify": true
    },
    "images": {
      "optimize": true
    },
    "html": {
      "pretty_urls": true
    },
    "skip": true
  }

This structure appears to be totally missing from the Open API specification.
