Provide the ability to get image size info without pulling images.

[MichaelSimons]

I have been asked a number of times by the .NET customers how to get the image sizes (compressed) after moving to MCR. It seems like this is something MCR should be exposing for our customers. I acknowledge the Docker Hub mechanism was flawed in that it was deceptive for multi-platform tags.

Example inquiry:
From dotnet/dotnet-docker#967 (comment) by @jonathann92
In docker hub I used to be able to see a "tags" columns and it would have all the previous tags and the size of the docker file.

Hi, I agree and this is something we will look to include it with in the Readme in the tabular display.

https://docs.docker.com/registry/spec/api/ <-- it seems like there might be some missing API specs. I get a lot of 404's
