Title: Send X-Docker-Endpoints at the end of a push

It looks like somewhere recently we stopped sending the registry server
that the images were uploaded to back to the index on the last step of the push
so basically in the index we don't know which registry the images were
pushed too.. not a big deal now since we only have one registry, but as we add multiple it
will cause problems. also makes it harder for me when I need to delete repos since I don't
really know which registry has the repositories.
