Handle HEAD requests as if they are GET requests

The Content-Type header is stripped by DRF when there is no body in the response.

Django and aiohttp both strip the body of HEAD requests. It is safe to handle HEAD requests the same as GET requests and rely on the web server to strip the body of the response.

This patch also adds the Content-Type header to the ManifestResponse objects which are used when responding to requests of Manifest creation.
