    Revert "Remove broken quota-classes API"

    This reverts commit 7d22153d05c67bb0bf4838efdb17b3360ec2e367.

    The quota_classes API was used to set default quota values
    so it shouldn't have been removed, so reverting a series
    of changes that removed the API and it's internal code.

     doc/api_samples/all_extensions/extensions-get-resp.xml
     nova/tests/integrated/api_samples/all_extensions/extensions-get-resp.xml.tpl

    The conflicts are due to Mark McLoughlin's timestamp-format series
    of changes on master (Juno).

    Also note that quota_classes.py was changed due to
    commit c75a15a4 to rename the NotAuthorized exception
    to Forbidden.
