* Clarify internal LB with external LB use case

* Clarify how to use both internal and external, non-cluster aware and
  not managed with Kubespray, LB solutions.
* Clarify the requirements, like TLS/SSL termination, for such an external LB.
  Unlike to the 'cluster-aware' external LB config, endpoints' security must be
  managed by that non-cluster aware external LB.
* Note that masters always contact their local apiservers via https://bip:sp.
  It's highly unlikely to go down and it reduces latency that might be
  introduced when going host->lb->host. Only computes go that path.
