The singleflight function was capturing the context.Context of the first caller that invoked the `singleflight.Do`. This could cause all concurrent calls to be cancelled when the first request is cancelled. singleflight calls were also moved from the ImageService to Daemon, to avoid having to implement this logic in both graphdriver and containerd based image services.
