Public bug reported:

If glance throws Internal Server Error (500) for some reason,
then in that case 'request-id' is not getting returned in response headers.

Request-id is required to analyse logs effectively on failure and it should be
returned from headers.

For ex. -

image-create api returns 500 error if property name exceeds 255 characters
(fix for this issue is in progress : https://review.openstack.org/#/c/203948/)

curl command:

$ curl -g -i -X POST -H 'Accept-Encoding: gzip, deflate' -H 'x-image-
meta-container_format: ami' -H 'x-image-meta-property-
