Fixed HAProxy's PROXY protocol v1 Human-readable header format in DialProxy
original code sent the header in the format: PROXY <family> <srcIP>
<srcPort> <dstIP> <dstPort>
according to docs header format should be:
PROXY <family> <srcIP> <dstIP> <srcPort> <dstPort>
this is according
to:
https://www.haproxy.org/download/1.8/doc/proxy-protocol.txt
section
2.1. Human-readable header format (Version 1).
