By default Calico blocks traffic from endpoints
to the host itself by using an iptables DROP
action. It could lead to a situation when service
has one alive endpoint, but pods which run on
the same node can not access it. Changed the action
to RETURN.
Kubernetes project is about to set etcdv3 as default storage engine in
1.6. This patch allows to specify particular backend for
kube-apiserver. User may force the option to etcdv3 for new environment.
At the same time if the environment uses v2 it will continue uses it
until user decides to upgrade to v3.

Operator can specify any port for kube-api (6443 default) This helps in
case where some pods such as Ingress require 443 exclusively.

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.
* 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

Sometimes, a sysadmin might outright delete the SELinux rpms and
delete the configuration. This causes the selinux module to fail
with
```
IOError: [Errno 2] No such file or directory: '/etc/selinux/config'\n",
"module_stdout": "", "msg": "MODULE FAILURE"}
```
This simply checks that /etc/selinux/config exists before we try
to set it Permissive.
Update from feedback
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.

Kubelet is responsible for creating symlinks from /var/lib/docker to /var/log
to make fluentd logging collector work.
However without using host's /var/log those links are invisible to fluentd.
This is done on rkt configuration too.
Based on #718 introduced by rsmitty.
Includes all roles and all options to support deployment of
new hosts in case they were added to inventory.
Main difference here is that master role is evaluated first
so that master components get upgraded first.
Fixes#694
- Refactor 'Check if bootstrap is needed' as ansible loop. This allows
to add new elements easily without refactoring. Add pip to the list.
- Refactor 'Install python 2.x' task to run once if any of rc
codes != 0. Actually, need_bootstrap is array of hashes, so map will
allow to get single array of rc statuses. So if status is not zero it
will be sorted and the last element will be get, converted to bool.

"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).
always_run was deprecated in Ansible 2.2 and will be removed in 2.4
ansible logs contain "[DEPRECATION WARNING]: always_run is deprecated.
Use check_mode = no instead". This patch fix deprecation.
Since systemd kubelet.service has {{ ssl_ca_dirs }}, fact should be
gathered before writing kubelet.service.
