* fix upgrade of crio on fcos
- update documents

* install conntrack required by kube-proxy
- like commit 48c41bcb

* enable fedora modular repo for crio

* allow to override crio configuration
- set cgroup manager same to kubelet_cgroup_driver if defined
- path of seccomp_profile depends on distribution

* allow to override crio configuration
- fix path for ubuntu

* allow to override crio configuration
- fix cni path for fcos

* Fix proxy and module_hotfixes

On CentOS 8 with proxy ansible render inline `proxy` and `module_hotfixes` options.

For example:

`proxy=http://127.0.0.1:3128module_hotfixes=True`

But expected result:

```
proxy=http://127.0.0.1:3128
module_hotfixes=True
```

* Use ini_file module for work with ini files

* Prevent duplicates proxy= option in /etc/yum.conf

Module `lineinfile` is weak, use most powerful module `ini_file` and add or remove `proxy=` when `http_proxy` is defined or not.

* fedora coreos support

* fedora coreos support
- add fcos documentations

Solves problem with mitogen about 'Compress object has no attribute copy' in zlib module.

* Merge OracleLinux in RedHat bootstrap-os

* Set default for use_oracle_public_repo in main.yaml

The 'regexp' parameter matches last occurrence of a line starting with 'proxy=' and replaces it with the one defined in 'line' parameter. If no match - it works same way as before. This fixes resuming cluster deployments failed after that task (if there was no more than one line starting with 'proxy' in the yum.conf file - this condition should also be reassured with the change introduced here) eg. if they were initiated with Terraform.

* Fix python3-libselinux installation for RHEL/CentOS 8

In bootstrap-centos.yml we haven't gathered the facts,
so #5127 couldn't work

Minimum ansible version to run kubespray is 2.7.8,
so ansible_distribution_major_version is defined an there is no need to default it

* Use python3-libselinux on RHEL8/Centos8

* The fact ansible_facts.distribution_major_version is not present on older Ansible version.
Default it to 0 in when not present and use libselinux-python as package to get current
default behaviour.

Updated Openstack to terraform 0.12 (#5062)

* update openstack to terraform 0.12(.5)

* replace cluter.tf with cluster.tfvars

* update README.md to terraform 0.12

* update Openstack CI tests to use terraform 0.12

* specify terraform version in openstack README

* gitlab CI to copy cluster.tfvars in case of openstack provider

* The terraform/openstack dynamic inventory can read
tfstate v4 (generated by terraform 0.12) and convert them internally

Additionally the script has been updated to Python 3.

Fixed Issue #1032

test case for OEL7 AIL with kubeadm

Add packet CI stuff for oracle 7

* Add support for http(s)_proxy to CoreOS and Fedora

* fix opensuse proxy support

* Fix CoreOS proxy support

* update documentation

* Add README to bootstrap-os role

* Rework bootstrap-os once more

* Document workarounds for bugs/deficiencies in Ansible modules
* Unify and document role variables
* Remove installation of additional packages and repositories
* Merge Ubuntu and Debian tasks
* Remove pipelining setting from default playbooks
* Fix OpenSUSE not running its required tasks

The docker service provided by the containers-basic bundle is masked
in ClearLinux distribution. This is causing errors in the following
steps. This commit ensures that the unit is not masked.

Based on the CephFS Provisioner Addon, the following changes have been made:
 - Upstream v2.1.1-k8s1.11
 - Configurable Provisioner replicas

* Vagrantfile: Bump openSUSE to Leap 15.0

* roles: container-engine: Add 'containerd' package for openSUSE

The 'containerd' package contains the docker-containerd and
docker-containerd-shim binaries. We also need to ensure that the latest
version is installed since an older version may already be present (eg GCE
images)

* Remove docker log-opts for opensuse

* roles: bootstrap-os: Use lowercase 'o' for openSUSE

OpenSUSE is not a valid family name. The correct one is openSUSE

* roles: bootstrap-os: Update zypper cache before first installation

The zypper cache may be outdated so ensure that it's fully updated
before we try and install the bootstrap packages.

* Fix bootsrap-os role, failing to create remote_tmp

* use ansible_remote_tmp hostvar

Omit does not work in the context of yum_repository proxy. The ansible documentation specifies to use _none_ to disable the global proxy setting. (#4225)

* bootstrap: rework role

* support being called from a non-root user
* run some commands in check mode
* unify spelling/task names

* bootstrap: fix wording of comments for check_mode: false

* bootstrap: remove setup-pipelining task

If a centos or rhel node is not configured with the extras repo installation of required packages (python-httplib2 in particular) will fail later on. (#4213)

Looks like `epel_enabled` was not configured for the epel install in `bootstrap-centos.yml`. Also, there were no conditionals that would trigger bootstrap for RHEL.

* remove os_family variable from bootstrap-os

* quote the conditions another time to fix the syntax error

* Fix mixup http/https in bootstrap-debian.yml

* Update bootstrap-debian.yml

* Update the version of pypy used on CoreOS bootstrap-os

* update the pip installation process on CoreOS

Add support install python-pip from local yum repository if local yum repository exist.
