3.7.4:
Schema: Extract method for manual_fields processing
Allows for easier customisation of manual_fields processing, for example to \ 
provide per-method manual fields. AutoSchema adds get_manual_fields, as the \ 
intended override point, and a utility method update_fields, to handle by-name \ 
field replacement from a list, which, in general, you are not expected to \ 
override.
