Afkham Azeez reopened SYNAPSE-360:
----------------------------------
We need to start the listeners at last, so that in dynamic LB, the LB can start
sending messages to a node only after its listeners have started

> There are some limitations in the current load balancer implementation. e.g.
> if we have 2 identical services in 2 different worker nodes, which are
> fronted by a synapse load balancer instance. In such a case, we need to
> provide 4 endpoints in the synapse.xml file. As can be seen, this is not a
> very scalable solution. Hence, I have implemented an dynamic load balancing
> mechanism where the application members are discovered at runtime, and the
> endpoint do not need to be statically specified in the synapse.xml file.
> Currently, the application endpoints are calculated by replacing the IP and
> port of the incoming request with that of the member to which this request
> will be forwarded to. I have only tested with HTTP/S for the moment. More
> details about the concept & design can be found here:
