Add Cloudflare integration adapter with real zone status

Implements testConnection and listResources against the Cloudflare API,
reporting the configured zone's real status (active/pending/etc) as a
resource. Fixed a bug where non-2xx responses with non-JSON bodies (e.g.
invalid zone ID) threw inside the JSON parse instead of failing cleanly.
