NIFI-2525: Fix Proxy auth issue with async send.
Without this fix, NiFi fails to send data via HTTP Site-to-Site through
Proxy which requires authentication due to AsynchronousCloseException.
It happens when async client replays producing contents in order to re-send the
request with auth credential for the proxy server, however the
connection is already closed.
This fix makes NiFi to send actual data only at the second round of requests,
so that flow-file
contents can be sent without reading it twice.

> Pulling data using Remote Process Group from output port works.
> However, pushing data using Remote Process Group to input port fails with
> AsynchronousCloseException.
> A RPG sends data via POST, then a proxy server returns 407: proxy auth
> required. After this, the RPG should resend the request with credential, but
> the data channel is already closed.
> Currently, it uses chunked encoding so that it can stream data to send.
> Sending actual data twice won't be efficient. We need to do the
> authentication before start reading flow-file stream.
