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 nova calls cinder.
But nova cannot output 'x-openstack-request-id' to the log( if the call is successful).
If nova outputs 'x-openstack-request-id' to the log, it will enable us to perform the analysis more efficiently.

Fix proposed to branch: master
Review: https://review.openstack.org/98967

[Joe Gordon (jogo)]

This is part of an existing blueprint: http://git.openstack.org/cgit/openstack/nova-specs/tree/specs/juno/cross-service-request-id.rst

[Takashi Natsume (natsume-takashi)]

The existing blueprint defines nova response header.
But this bug report is about log output of cinder response header.

[Chris Buccella (chris-buccella)]

I think jogo meant to link to this blueprint: http://git.openstack.org/cgit/openstack/nova-specs/tree/specs/juno/log-request-id-mappings.rst
