Add a Python3 only serializer that relies on 3.7+ dicts being ordered.
Reduces the time to serialize by about 40%.
Need to set factory.json_serializer to "fast" to enable this.
Also:
fixes some production_mode issues.
adds a "off" flag to production_mode to reset the flags (but can't un-cache the hierarchy)
put a test around required properties for validation
