[PATCH v2 15/23] docs/qapidoc: add add_field() and generate_field() helper methods

[John Snow]

These are simple rST generation methods that assist in getting the types
and formatting correct for a field list entry. add_field() is a more
raw, direct call while generate_field() is intended to be used for
generating the correct field from a member object.
