Add --os-endpoint-type to match other services

Cinder uses the parameter '--endpoint-type' but other services
 (Glance, Nova, Swift) use '--os-endpoint-type'. (Neutron has deprecated
 'endpoint-type' in favor or 'os-endpoint-type' as well.
'--endpoint-type' should be deprecated and 'os-endpoint-type' should
be added.
