Updated GRPC to 1.12, which forced me to update everything else and vendor SwarmKit to moby/swarmkit#2649

[dmcgowan]

Finally green tests, I am going to remove the blocked marker and update swarmkit to the merged version

Looks like you need to vendor with an older version of vndr (can do it inside the build container);

The result of vndr differs

Green now

LGTM

Looks like the bump of gRPC caused a regression, because grpc now adds a limit that was not previously set; As of grpc/grpc-go@50d4175 / grpc/grpc-go@6f8b553 (grpc/grpc-go#1165) a limit of 4MB is applied, which can cause issues with many tasks running.

See #38103 and #37997
