Container Support

Based on the number of blob a container is based of, pulp-container will return a 500

A simple upload - Everything works fine

#> podman push --tls-verify=false 192.168.121.209/alpine:latest                                                                                                                         
Getting image source signatures
Copying blob f4666769fca7 done  
Copying config b14afc6dfb done  
Writing manifest to image destination
Storing signatures

More layered container - 500 is returned
