openstack/nova - nova - OpenDev: Free Software Needs Free Tools

As discussed at summit, the version part of the URL is not really
relevant, or a thing a user should be filling out themselves, this
should instead be set by the service catalog and extracted from the
token.
This removes it's reference in all documented REST urls, and adds a
new section describing how one gets the base URL for all calls.

This adds a set of tags in comments to the beginning of files so that
we can process them according to the documentation here:

This removes the final warnings from the api-ref code base, and flips
the sphinx switch to enforce warnings as errors.
It also adds code to the rest_parameters extension to make it more
clear where a problem is when it comes to included parameters. This
puts us in a place where we can start doing the file per file look at
content.

This fixes the samples references for ``servers-actions.inc`` and
``servers-multiple-create.inc`` and drops the warnings count to 195.

In the sphinx document h3 is supposed to be '-' not '^':
=, for sections
-, for subsections
^, for subsubsections
We have to enforce consistency here because we're processing included
files which all have to agree, otherwise it's a sphinx error.

This is the results of the RST conversion from WADL. It creates a
single index plus a bunch of included files which represent sections
of the API document. This is the starting point for fixing the
documentation.
