* 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.

This does not update v1.9.0, but fixes two incompatibilities
when trying to deploy v1.9.0.

Starting with Kubernetes v1.8.4, kubelet ignores the AWS cloud
provider string and uses the override hostname, which fails
Node admission checks.

Fixes #2094

Renaming runtime docker_version to prevent setting that
value on the command line from breaking the play run.

This fixes #2081

Add possibility to create default OpenStack Cinder Storage Class

Closes: #1609

Ansible cannot seem to handle omitting delegate_to since v2.4.0.0.

As we have seen with other containers, sometimes container removal fails on the first attempt due to some Docker bugs. Retrying typically corrects the issue.
