[SPARK-11140] [core] Transfer files using network lib when using
NettyRpcEnv.
This change abstracts the code that serves jars / files to executors so that
each RpcEnv can have its own implementation; the akka version uses the
existing
HTTP-based file serving mechanism, while the netty versions uses the new
stream support added to the network lib, which makes file transfers benefit
from the easier security configuration of the network library, and should
also
reduce overhead overall.
The change includes a small fix to TransportChannelHandler so that it
propagates
user events to downstream handlers.
