This creates a stub for landing content to support having the source
for the api-ref site in our source tree. It includes a new sphinx
extension that will be used to generate the html needed for the site
which supports 2 new stanzas:
.. rest_parameters::
This uses a parameters yaml file to look up the definitions of
parameters and produce a structured table of those parameters and how
they are used.
.. rest_method::
This is a stanza used inside a section which specifies the REST method
(i.e. GET /servers/{id}) which is then used to produce a nice
collapsable section.
This uses quite a bit of the sphinx extension API, and tries to
document any non obvious actions.
This extension needs additional styling from bootstrap, and some
custom js / css to do the theming / collapsing. That's included as
part of this.
