---------------------------------------------

updateNetworkOffering with maxconnections is throwing up error. Also don't see the concurrent_connections in network_offerings table.

> 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;
