> Some networks will kill idle connections if no data is transfered over them within a set amount of time. For example, using AWS's Elastic Load Balancer (ELB), the default time to kill a connection is only 60s! Because of this, we need a way to send application level heartbeats to keep these connections alive for any long running LAUNCH_NESTED_CONTAINER_SESSION, ATTACH_CONTAINER_INPUT and ATTACH_CONTAINER_OUTPUT calls. 
> We should serve these heartbeats from the IOSwitchboard server rather than the agent handlers since the agent essentially acts as a proxy and the heartbeats should originate from the actual server being communicated with.
