Why delegate the fetching data Future into the same tokio runtime rather than directly run to the end of future handle_prefetch_requests . Moreover, it seems the runtime rt only has a thread, so re-generate a future is efficent ?

The current future acts as a dispatcher, which receives requests from the mpmc queue and dispatch them.
So there may be multiple inflight requests.
Currently two inlfight-requests are allowed.
Try to amplify prefetch request for v6 image to reduce network requests. Signed-off-by: Jiang Liu <gerry@linux.alibaba.com>
Limit number of inflight prefetch requests per thread, to give higher priority to on-demand requests. Signed-off-by: Jiang Liu <gerry@linux.alibaba.com>

Reduce backend network IOs by enabling amplification of v6 prefetch requests. For a java image, it could reduce 50% network requests by average.
