------------------------------------

I think it is quite useful to get the memory details of Netty, so I'm trying to get another shot on this issue (https://github.com/apache/spark/pull/18935).

> The default network transportation is netty, and when transfering blocks for shuffle, the network layer will consume a decent size of memory, we shall collect the memory usage of this part and expose it.
