Add x-openstack-request-id header

Registered by Tan Lin on 2015-10-13

In order to track operations cross projects, many services like Nova/Glance/Neutron/Cinder/Keystone have a such header with HTTP responsed.
 Nova: https://blueprints.launchpad.net/nova/+spec/cross-service-request-id
 Cinder: https://blueprints.launchpad.net/cinder/+spec/add-standard-req-id-header
 HEAT: https://bugs.launchpad.net/heat/+bug/1324065

You can get this header from above projects by calling corresponding client with debug option.
Ironic should support this.

Approving as the implementation should be simple, and the cross-project spec describes most of how this should work.

We're moving from using blueprints to track features to RFE bugs. I've filed one for your change (see related bugs section). Please track further work there using Closes-Bug, Partial-Bug or Related-Bug in commit messages and use this newly created RFE bug.
