Mark the v1 API as deprecated

The Volume API spec says that the v1 should be marked as "DEPRECATED"
when querying the version[1]. However, when that API was deprecated in
dce0424d9, it was marked as "SUPPORTED", so there is a conflict between
the spec and the actual behavior. This patch updates the query to match
the documentation. This affects how keystoneauth discovers versions.
