CLOUDSTACK-7841: Gracefully reload haproxy config

The old way would disconnect all the existing connections through haproxy when
reload the config.

This new way would ensure that all the existing connections would still alive
after reload the config.

> Applying load balancer rules breaks existing connections and causes short outage.
> That's because our currently logic of handling haproxy reload configuration is not graceful
enough, and focused on how to recover from failed newly configuration.
> There would be a way to improve this.
