* 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
* Fix recover-control-plane to work with etcd 3.3.x and add CI
* Set default values for testcase
* Add actual test jobs
* Attempt to satisty gitlab ci linter
* Fix ansible targets
* Set etcd_member_name as stated in the docs...
* Recovering from 0 masters is not supported yet
* Add other master to broken_kube-master group as well
* Increase number of retries to see if etcd needs more time to heal
* Make number of retries for ETCD loops configurable, increase it for recovery CI and document it
* 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
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
Some installation are failing to authenticate with peers due to
etcd picking up/resoling the wrong node.
By setting 'etcd_peer_client_auth' to "False" you can disable peer client cert
authentication.

* Added update CA trust step for etcd and kube/secrets roles
* Added load_balancer_domain_name to certificate alt names if defined. Reset CA's in RedHat os.
* Rename kube-cluster-ca.crt to vault-ca.crt, we need separated CA`s for vault, etcd and kube.
* Vault role refactoring, remove optional cert vault auth because not not used and worked. Create separate CA`s fro vault and etcd.
* Fixed different certificates set for vault cert_managment
* Update doc/vault.md
* Fixed condition create vault CA, wrong group
* Fixed missing etcd_cert_path mount for rkt deployment type. Distribute vault roles for all vault hosts
* Removed wrong when condition in create etcd role vault tasks.
* Adding yaml linter to ci check
* Minor linting fixes from yamllint
* Changing CI to install python pkgs from requirements.txt
- adding in a secondary requirements.txt for tests
- moving yamllint to tests requirements
Reduce election timeout to 5000ms (was 10000ms)
Raise heartbeat interval to 250ms (was 100ms)
Remove etcd cpu share (was 300)
Make etcd_cpu_limit and etcd_memory_limit optional.
* Drop linux capabilities for unprivileged containerized
worlkoads Kargo configures for deployments.
* Configure required securityContext/user/group/groups for kube
components' static manifests, etcd, calico-rr and k8s apps,
like dnsmasq daemonset.
* Rework cloud-init (etcd) users creation for CoreOS.
* Fix nologin paths, adjust defaults for addusers role and ensure
supplementary groups membership added for users.
* Add netplug user for network plugins (yet unused by privileged
networking containers though).
* Grant the kube and netplug users read access for etcd certs via
the etcd certs group.
* Grant group read access to kube certs via the kube cert group.
* Remove priveleged mode for calico-rr and run it under its uid/gid
and supplementary etcd_cert group.
* Adjust docs.
* Align cpu/memory limits and dropped caps with added rkt support
for control plane.

* Add restart for weave service unit
* Reuse docker_bin_dir everythere
* Limit systemd managed docker containers by CPU/RAM. Do not configure native
systemd limits due to the lack of consensus in the kernel community
requires out-of-tree kernel patches.

Move version/repo vars to download role.
Add container to download params, which overrides url/source_url,
if enabled.

Improved docker reload command to wait for etcd to be
up before proceeding. Switched reload to run restart
because it can't reload if it is not guaranteed to be
in running state.
Running etcd in Docker reduces the number of individual file
downloads and services running on the host.
Note: etcd container v3.0.1 moves bindir to /usr/local/bin
Fixes: #298
