* 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
* Added custom ips to etcd vault distributed certificates
* Added custom ips to kube-master vault distributed certificates
* Added comment about issue_cert_copy_ca var in vault/issue_cert role file
* Generate kube-proxy, controller-manager and scheduler certificates by vault
* Revert "Disable vault from CI (#1546)"
This reverts commit 781f31d2b8.
* Fixed upgrade cluster with vault cert manager
* Remove vault dir in reset playbook
* Bump tag for upgrade CI, fix netchecker upgrade
netchecker-server was changed from pod to deployment, so
we need an upgrade hook for it.
CI now uses v2.1.1 as a basis for upgrade.
* Fix upgrades for certs from non-rbac to rbac
It is now possible to deactivate selected authentication methods
(basic auth, token auth) inside the cluster by adding
removing the required arguments to the Kube API Server and generating
the secrets accordingly.
The x509 authentification is currently not optional because disabling it
would affect the kubectl clients deployed on the master nodes.
Issue #1125. Make RBAC authorization plugin work out of the box.
"When bootstrapping, superuser credentials should include the system:masters group, for example by creating a client cert with /O=system:masters. This gives those credentials full access to the API and allows an admin to then set up bindings for other users."
* Leave all.yml to keep only optional vars
* Store groups' specific vars by existing group names
* Fix optional vars casted as mandatory (add default())
* Fix missing defaults for an optional IP var
* Relink group_vars for terraform to reflect changes

Migrate older inline= syntax to pure yml syntax for module args as to be consistant with most of the rest of the tasks
Cleanup some spacing in various files
Rename some files named yaml to yml for consistancy
"shell" step doesn't support check mode, which currently leads to failures,
when Ansible is being run in check mode (because Ansible doesn't run command,
assuming that command might have effect, and no "rc" or "output" is registered).
Setting "check_mode: no" allows to run those "shell" commands in check mode
(which is safe, because those shell commands doesn't have side effects).
- Docker 1.12 and further don't need nsenter hack. This patch removes
it. Also, it bumps the minimal version to 1.12.

* 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.

be run by limit on each node without regard for order.
The changes make sure that all of the directories needed to do
certificate management are on the master[0] or etcd[0] node regardless
of when the playbook gets run on each node. This allows for separate
ansible playbook runs in parallel that don't have to be synchronized.
the openssl tools will fail to create signing requests because
the CN is too long. This is mainly a problem when FQDNs are used
in the inventory file.
THis will truncate the hostname for the CN field only at the
first dot. This should handle the issue for most cases.
Add BGP route reflectors support in order to optimize BGP topology
for deployments with Calico network plugin.
Also bump version of calico/ctl for some bug fixes.
Also place in global vars and do not repeat the kube_*_config_dir
and kube_namespace vars for better code maintainability and UX.

Uses tar and register because synchronize module cannot sudo on the
remote side correctly and copy is too slow.
This patch dramatically cuts down the number of tasks to process
for cert synchronization.
* Don't push containers if not changed
* Do preinstall role only once and redistribute defaults to
corresponding roles

Also adds all masters by hostname and localhost/127.0.0.1 to
apiserver SSL certificate.
Includes documentation update on how localhost loadbalancer works.
Shorten deployment time with:
- Remove redundand roles if duplicated by a dependency and vice versa
- When a member of k8s-cluster, always install docker as a dependency
of the etcd role and drop the docker role from cluster.yaml.
- Drop etcd and node role dependencies from master role as they are
covered by the node role in k8s-cluster group as well. Copy defaults
for master from node role.
- Decouple master, node, secrets roles handlers and vars to be used w/o
cross references.

check_certs task "Check_certs | Set 'sync_certs' to true" was failing
due to the dict not existing, this sets defaults that allows the
correct behavior of the conditionals.
