Standalone etcd nodes do not generate node-$hostname certs and do
not need this serial calculated.

* do it like in kubernetes/secrets

* fix indentation

* processed comments

* missed one, sorry

* trailing space fix

Replace shell with command in order to allow the task to fail when openssl x509 does return zero (#3516)

* Fix ansible syntax to avoid ansible warnings (again)

* warn: false on tar -cfz

* wrong placement of warn:false

* Ability to specify ssl certificate duration and ssl key size - etcd/secrets

* Ability to specify ssl certificate duration and ssl key size - helm/contiv + fix contiv missing copy certs generation script

ensure there is pin priority for docker package to avoid upgrade of docker to incompatible version

remove empty when line

ensure there is pin priority for docker package to avoid upgrade of docker to incompatible version

force kubeadm upgrade due to failure without --force flag

ensure there is pin priority for docker package to avoid upgrade of docker to incompatible version

added nodeSelector to have compatibility with hybrid cluster with win nodes, also fix for download with missing container type

some cleanup for innecesary lines

remove conditions for nodeselector

Trigger reboot handler when version upgrade during update script

apiserver cert should be created only once

* Add tags for cert serial tasks

This will help facilitate tag-based deployment of specific components.

* fixup kubernetes node

* Move front-proxy-client certs back to kube mount

We want the same CA for all k8s certs

* Refactor vault to use a third party module

The module adds idempotency and reduces some of the repetitive
logic in the vault role

Requires ansible-modules-hashivault on ansible node and hvac
on the vault hosts themselves

Add upgrade test scenario
Remove bootstrap-os tags from tasks

* fix upgrade issues

* improve unseal logic

* specify ca and fix etcd check

* Fix initialization check

bump machine size

This reverts commit 51f4e658.

Add path for certificate location for SUSE distributions. Also make sure
the 'update-ca-certificates' command is executed on SUSE hosts as well.

The current way to setup the etc cluster is messy and buggy.

- It checks for cluster is healthy before the cluster is even created.
- The unit files are started on handlers, not in the task, so you mess with "flush handlers".
- The join_member.yml is not used.
- etcd events cluster is not configured for kubeadm
- remove duplicate runs between running the role on etcd nodes and k8s nodes

* Update etcd deployment to use correct cert and key

* Update to use admin cert for etcdctl commands

* Update handler to use admin cert too

Kubernetes makes this namespace automatically, so there is
no need for kubespray to manage it.
