30cc7c847e Reconfigure docker restart behavior on atomic 
Before restarting docker, instruct it to kill running
containers when it restarts.

Needs a second docker restart after we restore the original
behavior, otherwise the next time docker is restarted by
an operator, it will unexpectedly bring down all running
containers.

a5bb24b886 Fix docker restart in atomic 
In atomic, containers are left running when docker is restarted.
When docker is restarted after the flannel config is put in place,
the docker0 interface isn't re-IPed because docker sees the running
containers and won't update the previous config.

This patch kills all the running containers after docker is stopped.
We can't simply `docker stop` the running containers, as they respawn
before we've got a chance to stop the docker daemon, so we need to
use runc to do this after dockerd is stopped.

Pod opbject is not reschedulable by kubernetes. It means that if node
with netchecker-server goes down, netchecker-server won't be scheduled
somewhere. This commit changes the type of netchecker-server to
Deployment, so netchecker-server will be scheduled on other nodes in
case of failures.

1cfe0beac0 Set ClusterFirstWithHostNet for Pods with hostnetwork: true 
In kubernetes 1.6 ClusterFirstWithHostNet was added as an option. In
accordance to it kubelet will generate resolv.conf based on own
resolv.conf. However, this doesn't create 'options', thus the proper
solution requires some investigation.

This patch sets the same resolv.conf for kubelet as host

c04a6254b9 Backup etcd data before restarting etcd 
etcd is crucial part of kubernetes cluster. Ansible restarts etcd on
reconfiguration. Backup helps operator to restore cluster manually in
case of any issues.

3a39904011 Move calico-policy-controller into separate role 
By default Calico CNI does not create any network access policies
or profiles if 'policy' is enabled in CNI config. And without any
policies/profiles network access to/from PODs is blocked.

K8s related policies are created by calico-policy-controller in
such case. So we need to start it as soon as possible, before any
real workloads.

This patch also fixes kube-api port in calico-policy-controller
yaml template.

Closes #1132

026da060f2 Granular authentication Control 
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.

  - fedora and redhat are placeholders/guesses
  - the "old" package repositories seem to have the "new" CE version which is `1.13.1` based
- `docker-ce` looks like it is named as a backported `docker-engine` package in some
  places

- Did not change the `defaults` version anywhere, so should work as before
- Did not point to new package repositories, as existing ones have the new packages.

Use docker-engine 1.13.1 
The default version of Docker was switched to 1.13 in #1059.  This
change also bumped ubuntu from installing docker-engine 1.13.0 to
1.13.1.  This PR updates os families which had 1.13 defined, but
were using 1.13.0.

The impetus for this change is an issue running tiller 1.2.3 on
docker 1.13.0.  See discussion [1][2].

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.

Safe disable SELinux

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

bff955ff7e Mount host's /var/log into kubelet container 
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.

7ab04b2e73 fix typo in "kibana_base_url" variable name 
This typo lead to kibana_base_url being undefined and Kibana used
default base URL ("/") which is incorrect with default proxy-based
access.

97ebbb9672 Add graceful upgrade process 
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.

09847567ae set "check_mode: no" for read-only "shell" steps that registers result 
"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.

- Exclude kubelet CPU/RAM (kube-reserved) from cgroup. It decreases a
  chance of overcommitment
- Add a possibility to modify Kubelet node-status-update-frequency
- Add a posibility to configure node-monitor-grace-period,
  node-monitor-period, pod-eviction-timeout for Kubernetes controller
  manager
- Add Kubernetes Relaibility Documentation with recomendations for
  various scenarios.
