Sean Dague 04f8612aa9 api-ref: complete verification for extensions resource
This completes all 4 phases of the extensions resource.

* List method was added
* Error codes updated as exist in code
* Updates parameters.yaml to match actual descriptions for parameters
* Update body to be a lot stronger about what our deprecation means and why.

=====================================
Extensions (extensions) (DEPRECATED)
=====================================
Lists available extensions and shows information for an extension, by
alias.
Nova originally supported the concept of API extensions, that allowed
implementations of Nova to change the API (add new resources, or
attributes to existing resource objects) via extensions. In an attempt
to expose to the user what was supported in a particular site, the
extensions resource provided a list of extensions and detailed
information on each. The net result was gratuitous differentiation in
the API that required all users of OpenStack clouds to write specific
code to interact with every cloud.
As such, the entire extensions concept is deprecated, and will be
removed in the near future.
For information about extensions, see `Extensions
<http://developer.openstack.org/api-guide/compute/extensions.html>`__.
