Description
Starting with docker client 20.10, a pull operation fails with the following message:
sudo docker pull pulp.example.com/test:manifest_a docker: Error response from daemon: missing or empty Content-Type header.
The logs for pulp show that a 200 response was sent:
127.0.0.1 - - [04/Feb/2021:15:48:33 +0000] "HEAD /v2/test/manifests/manifest_a HTTP/1.0" 200 4 "-"

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.
