nova volume-* managers override service_type to 'volume', which is missed in gates

[Andriy Kurilin]

An example of override: https://github.com/openstack/python-novaclient/blob/f1ea28349bb8e3a79457137e4d06bb599b30b6c6/novaclient/v2/volumes.py#L71

Service_type 'volume' is missed in gates due to disabling Cinder API V1. See thread http://lists.openstack.org/pipermail/openstack-dev/2015-September/075689.html for more details

    Change default service_type for volumes managers

    Currently, novaclient's gates are broken due to missed 'volume' service_type.
    This patch changes default service type for all volume related managers to
    "volumev2" and leave ability to set "volume" service_type.
