wanghui de4d72c5f2 Use openstackdocstheme according to guide
This change alters the api-ref's conf.py to follow the documentation[1].
Functionally, this results in the api-ref using the api_ref theme
options, which adds a dropdown menu to the other API references instead
of to unrelated documentation, and deduplicates the headers.
