Currently apache access logs have controller ips instead of source ips
recorded since apache simply records source ip of http traffic.
This change ensures that client ips are detected by the X-Forwarded-For
header added by haproxy.
Note that the forwarded format does not log client ip if the header is
missing. Because of this, direct http requests(eg. healthcheck requests
from haproxy) results in log lines without client ip.
