Proxy Protocol support for TCP harvester

[jalaziz]

We have a use case where we have a bridge behind a TCP proxy. This is useful as a method to share port 443 with multiple services on the server. The issue with this approach is that ice4J doesn't see the correct remote address.

While not strictly a problem, it would be great if ice4J could support the proxy protocol on TCP connections. This would, at the very least, allow logs to show the correct remote host addresses.
