Concurrent uploads which share layers worked correctly as of moby#18353, but unfortunately moby#18785 caused a regression. This PR removed the logic that shares digests between different push sessions. This overlooked the case where one session was waiting for another session to upload a layer. This commit adds back the ability to propagate this digest information, using the distribution.Descriptor type because this is what is received from stats and uploads, and also what is ultimately needed for building the manifest. Surprisingly, there was no test covering this case. This commit adds one. It fails without the fix. See recent comments on moby#9132. Signed-off-by: Aaron Lehmann <aaron.lehmann@docker.com>

Fix concurrent uploads that share layers
|
@aaronlehmann I saw you got a panic when reproducing the issue; #9132 (comment). Should this be given an "priority/P.."? i.e. is it serious enough to warrant a patch release? |

If there is a 1.10.3 release, this should be included. |
