this is not complete -- there are almost certainly more instances of
this issue

and fix the one with side effect.

Also removes `notify` from this task as the task has `changed_when: false`
and notify is not going to fire.

This reverts commit c0e1211a.

* etcd: enable v2 api only if needed

Only enable v2 API if we have a consumer (flannel)
This reduce the exposed surface for etcd.

* Fix bad group name

* Ansible: move to Ansible 3.4.0 which uses ansible-base 2.10.10

* Docs: add a note about ansible upgrade post 2.9.x

* CI: ensure ansible is removed before ansible 3.x is installed to avoid pip failures

* Ansible: use newer ansible-lint

* Fix ansible-lint 5.0.11 found issues

* syntax issues
* risky-file-permissions
* var-naming
* role-name
* molecule tests

* Mitogen: use 0.3.0rc1 which adds support for ansible 2.10+

* Pin ansible-base to 2.10.11 to get package fix on RHEL8

* Remove the duplicate task in etcd role

* Remove inessential delegate_to

* rename ansible groups to use _ instead of -

k8s-cluster -> k8s_cluster
k8s-node -> k8s_node
calico-rr -> calico_rr
no-floating -> no_floating

Note: kube-node,k8s-cluster groups in upgrade CI
      need clean-up after v2.16 is tagged

* ensure old groups are mapped to the new ones

* Remove contrib/vault

This is marked as broken since 2018 / 3dcb9146
This still reference apiserver.pem, not used since ddffdb63

By default Ansible stat module compute checksum, list extended attributes and find mime type
To find all stat invocations that really use one of those:
git grep -F stat. | grep -vE 'stat.(islnk|exists|lnk_source|writeable)'

* Added force_etcd_cert_refresh var to maintain existing functionality. Broke out etcd node cert syncing from member and admin cert sync logic. Now first etcd will sync node certs to other etcd members on every run to keep all etcds up to date after adding additional worker nodes to the cluster

* Updated etcd cert check tasks to better detect when new certificates need to be generated

* Move usage of force_etcd_cert_refresh var to gen_certs fact set

* Force etcd cert generation per server if force_etcd_cert_refresh is set to true

* Include gathering of node certs even if k8s-cluster member and in etcd group.

* Removed run_once due to when statement

* Add downlaod bin tasks

* Add tags never and etcd

* yamllint

* Add etcd tls cipher suites

* yamllint

* fixed bug in etcd retention where backups are not sorted by date

* added directory filter to find command

* added an ansible var to manage retention of etcd backups

* refactord ls/grep into find in etcd backup removal command

Remove task with install etcdctl from etcd role when etcd_kubeadm_enabled=true

* change /etc/ssl/etcd to etcd_config_dir param

* add use etcd_events_data_dir param
