>         Environment: Master, Xen

> In core//src/com/cloud/network/HAProxyConfigurator.java, maxconn is hardcoded to 4096.
According to the HAProxy page, it is safe to assume 20k connections per GB of RAM. This parameter
can be changed by the patches/systemvm/debian/config/root/reconfigLB.sh to be based on the
actual RAM of the VR.
> During testing following observations were made..
> - /etc/haproxy/haproxy.cfg doesnt have maxconn as global variable.
> - patches/systemvm/debian/config/root/reconfigLB.sh doesnt configure HAProxy.cfg as per
VR service offering and available RAM;
