    Accept Range requests and set appropriate response
    
    Currently glance v2 API incorrectly accepts ‘Content-Range’ header
    for random image access and does not set response headers.
    As per rfc7233, ‘Range’ requests should be accepted and ‘Content-Range’
    must be returned in the response headers.
    
    This patch enables Glance v2 API to accept the more appropriate ‘Range’
    requests and sets ‘Content-Range’ response header.
    
    For backward compatibility with pre-Pike Glance clients, the incorrect
    'Content-Range' header will be accepted silently in perpetuity.
    Thus this patch contains tests for 'Content-Range' in requests to
    prevent regressions.

Title:
  Glance does not accept 'Range' in requests.

Status in Glance:
  Fix Released

Bug description:
  Glance currently supports partial download requests if provided with a Content-Range header in the GET request. [1]
  However, Glance needs to add support for 'Range' requests and serve partial image download requests accordingly as per rfc7233. [2]
