The 'x-openstack-request-id' from cinder cannot be output to the log.

[Takashi Natsume]

Cinder returns a response including 'x-openstack-request-id' in the HTTP response header when heat calls cinder.
But heat cannot output 'x-openstack-request-id' to the log( if the call is successful).
If heat outputs 'x-openstack-request-id' to the log, it will enable us to perform the analysis more efficiently.
