This patch changes the [haproxy_amphora] connection_max_retries and
build_active_retries default values from 300 to 120. This means load
balancer builds will wait for ten minutes instead of twenty-five minutes
for nova to boot the virtual machine.
We feel these are more reasonable default values for most production
deployments and provide a better user experience.
Only environments running in nested virtualization, without nested
virtualization enabled in the hypervisor could require a value as high as
300.
