This commit adapts the "Lay Down KubeDNS Template" task to use the static
files moved by pull request [1]

[1] https://github.com/kubernetes-sigs/kubespray/pull/4341

* Fix bootsrap-os role, failing to create remote_tmp

* use ansible_remote_tmp hostvar

values from inventory in roles/kubespray-defaults/defaults/main.yml
hardcoded values in roles/container-engine/defaults/main.yml

dns_servers set empty in roles/container-engine/defaults/main.yml and skydns_server not set in docker_dns_servers variables
also set default value for manual_dns_serve

another variables in roles/container-engine/defaults not need to set

* Added configurable local apiserver proxy liveness probe

* Enable API LB healthcheck by default

* Fix template spacing and moved healthz location to nginx http section

* Fix healthcheck listen address to allow kubelet request healthcheck

Upgrade to k8s 1.13.5

* Added support of bastion host for reset.yaml

* Empty commit to triger CI

This reverts commit ea7a6f1c.

This change modified the certs dir for Kubernetes, but did not move the directories for existing clusters.

On CoreOS, without this, it fails to kubectl apply MetalLB due to lack of privileges.

Pods on down/unresponsive nodes can't be deleted without
--force --grace-period=0.

Fixes #4314

* Move most coredns templates to static files

This should speed up the task slightly

Helpful for local development but also in production workloads (once the

replication)

* fix(local-path-provisioner): jinja template syntax: if condition white space

kube ansible module can be used with recursive: true
which sill process the directory used in -f, --filename recursively

The openstackclient is the preferred CLI for OpenStack
environments and should be used instead of novaclient.
