Use --os-endpoint-type for Cinder CLI

The --endpoint-type option has been deprecated in Cinder for several
years and was just recently removed. It was missed that the tempest lib
CLI code was still using that to specify the public URL. This updates
the Cinder CLI handling to use the more conventional --os-endpoint-type.
