    Import the config drive docs from openstack-manuals

    As part of the docs migration from openstack-manuals to
    nova in the pike release we missed the config-drive docs.

    This change does the following:

    1. Imports the config-drive doc into the user guide.
    2. Fixes a broken link to the metadata service in the doc.
    3. Removes a note about liberty being the current release.
    4. Adds a link in the API reference parameters to actually
       point at the document we have in tree now, which is
       otherwise not very discoverable as the main index does
       not link to this page (or the user index for that matter).
