* Add proxy support to CRI-O service

The crio.service requires proxy environment variables when it's
deployed behind a corporated network. This change creates a systemd
configuration file when the proxy variables are defined.

* Remove unnecesary crio's tasks

* Fix kube-proxy ds nodeselector for older versions

* Fix for ansible-lint

The playbook that bootstrap openSUSE servers assumes that the
/etc/sysconfig/proxy file exists but the execution fails when
these file is not present. This change guarantees its existence.

* assembly fallback_ips and no_proxy var only one time on localhost and populate result on all hosts

* add tag always, fix ansible lint errors

* workaround to mitogen issue dw/mitogen#663

* do not gather fact before install python on coreos like distros

* try to pass docker molecule test

* Generate unique username per cluster

* rename admin kubeconfig shell output to raw_admin_kubeconfig

* Make the linter happy

* Cleaning up tasks

* Add Molecule for container-engine/docker

* Add bootstrap-os to Molecule prepare stage

* Customize PodSecurityPolicies from inventory

* Fixed yaml indentation

* Add CI_TEST_VARS to tests

* Update flannel to 0.12.0 (with new manifests) and disable tx/rx
offloading in networking test

* fix upgrade of crio on fcos

* 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

Update Calico to v3.13.2, Multus to v3.4.1. Add ConfigMap get permission to allow calico-node access to kubeadm config. (#5912)

* 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.
