Task: create RST from Docbook plus WADL source that can use Sphinx directives for reference info

[Anne Gentle]

This task is basically the outlined solution from Sean Dague, to make a proof of concept.

POC here:
http://docs-draft.openstack.org/86/295486/4/check/gate-nova-docs/eb4be7c//doc/build/html/rest_api/servers.html#list-servers-lists-ids-names-and-links-for-all-servers
REST drop downs working
rest_method and rest_parameters stanzas
Input RST format - https://raw.githubusercontent.com/openstack/nova/e8afd02ca66a0801974ba2199c5323736c606257/doc/source/rest_api/servers.rst
Parameter Lookup file that's used - https://github.com/openstack/nova/blob/e8afd02ca66a0801974ba2199c5323736c606257/doc/source/rest_api/parameters.yaml
Microversions on parameters https://github.com/openstack/nova/blob/e8afd02ca66a0801974ba2199c5323736c606257/doc/source/rest_api/parameters.yaml#L605 which also set css class attributes, which could have JS make them display: none if we were filtering based on mv.C
