If there is a loadbalancer that sits between NSX and neutron usually it has a default http_timeout on long lived http_connections. This can cause connections that have not been used from neutron to nsx to be reset after sometime. This patch makes the amount time we wait to reconnect the connection configurable so one can set it to match the balancer timeout to avoid having to try the connection if the loadbalaner has already timed it out. closes-bug #1382000 Change-Id: Ifca76ca6c24a2002b46b1935fbb4fc63f15c5af1
