Updates based on feedback
Simplify checks for file exists
remove invalid char
Review feedback. Use regular systemd file.
Add template for docker systemd atomic
When a apiserver_loadbalancer_domain_name is added to the Openssl.conf
the counter gets not increased correctly. This didnt seem to have an
effect at the current kargo version.
New deploy modes: scale, ha-scale, separate-scale
Creates 200 fake hosts for deployment with fake hostvars.
Useful for testing certificate generation and propagation to other
master nodes.
Updated test cases descriptions.
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
Ansible playbook fails when tags are limited to "facts,etcd" or to
"facts". This patch allows to run ansible-playbook to gather facts only
that don't require calico/flannel/weave components to be verified. This
allows to run ansible with 'facts,bootstrap-os' or just 'facts' to
gether facts that don't require specific components.

"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).
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.

systemctl daemon-reload should be run before when task modifies/creates
union for etcd. Otherwise etcd won't be able to start

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.
"etcd_node_cert_data" variable is undefinded for "calico-rr" role.
This patch adds "calico-rr" nodes to task where "etcd_node_cert_data"
variable is registered.
* 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.
