cinder-api exception due to default_volume_type not being created

[Steve Hindle]

In cinder-api.log we get VolumeTypeNotFoundByName errors
( grep 'raise exception.VolumeTypeNotFoundByName' cinder-api.log)

This is due to setting 'default_volume_type' ( = rbd-1, for ceph storage) in /etc/cinder.conf,
but NOT doing a 'cinder type-create' for the volume type. We can eliminate this error two ways:
  1.) Removed the default_volume_type in cinder.conf
  2.) Add a 'cinder type-create' similiar to the following:
         # cinder type-create rbd-1
         # cinder type-key rbd-1 set volume_backend_name=rbd-1

You should either stop setting default_volume_type and assume that without manual setup Kolla will create volumes without volume type, or create a volume type for default backend. In general volume_type!=backend_name.
