Support is added for the `2.67 microversion`_ which allows specifying
a ``volume_type`` with the ``--block-device`` option on the ``nova boot``
command. The ``novaclient.v2.servers.ServerManager.create()`` method now
also supports a ``volume_type`` entry in the ``block_device_mapping_v2``
parameter.
