Create an origin cloud region mapping

POST/zones/{zone_id}/cache/origin_cloud_regions

Adds a single IP-to-cloud-region mapping for the zone. The IP must be a valid IPv4 or IPv6 address and is normalized to canonical form before storage (RFC 5952 for IPv6). Returns 400 (code 1145) if a mapping for that IP already exists — use PATCH to update an existing entry. The vendor and region are validated against the list from GET /zones/{zone_id}/cache/origin_cloud_regions/supported_regions.
