Add GET and DELETE endpoints for Docker blob uploads (#21367)

Browse source 
This PR adds support for
https://docs.docker.com/registry/spec/api/#get-blob-upload
https://docs.docker.com/registry/spec/api/#delete-blob-upload

Both are not required by the OCI spec but some clients call these
endpoints.
