"list API versions" API returns wrong version number in media-types

[Ken'ichi Ohmichi]

Now Cinder returns the following response on "list API versions" and "version=" is always "1" on v2 and v3 APIs also.
On the other projects, Nova returns version numbers like "2.1" on the same format, and Keystone also returns version numbers with different format like "application/vnd.openstack.identity-v3+json", "application/vnd.openstack.identity-v2.0+json".
So it would be better to change the version numbers into accurate numbers.

    Fix version numbers on media-types

    On "list API versions", 'media-types' type needed to show the version
    number as "version=". However all versions represent "1" always.
    It is confusing, so this patch fixes them for accurate ones.
