no_proxy is a pain to get right, and having proxy variables present causes issues
(k8s components get proxy configuration after upgrade, see #7100)
It's better to only configure what require proxy:
- the runtime (containerd/docker/crio)
- the package manager + apt_key
- the download tasks
Tested with the following clusters
- 4 CentOS 8 nodes
- 1 Ubuntu 20.04 node

Upgrading docker / containerd without adapting the configuration might break the node,
so disable docker-ce repo by default.
We are already using dpkg hold for Debian.
All containerd.io packages provide /usr/bin/runc, so no need to check
yum_conf was never used for containerd
module_hotfixes should not be needed with the EL8 repo

* Ensure libseccomp is installed before starting containerd on CentOS 8
* Simplify libseccomp install on CentOS 8
- Uses `package` module
- Replaces complex version check with 'state: latest'. The version must
be > 2.3 when using with cri-o.
- Removes unnecessary `not is_ostree` condition as CentOS 8 does not use
ostree
* 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.

This 38688a4486 change replaces the
value for dockerproject_.+_repo_.+ docker variables but their new
value was previously defined in other variables. This change removes
the dockerproject_.+_repo_.+ docker variables in favor of the older
ones.
* Change dockerproject.org to download.docker.com
dockerproject.org was deprecated in 2017 and has gone down.
* Restore yum repo for containerd

* 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The zypper cache may be outdated so ensure that it's fully updated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.
Both the `yum` and `apt` modules support a list as input, this allows us avoid the slower `with_items` approach, which can take a long time with a large count of cluster nodes.
Both kubedns and dnsmasq modes are long not maintained.
We should run dns_late steps at the end because sshd
makes DNS lookups during Ansible run and has 2s timeouts
for each failed lookup trying to connect to coredns before
it is ready.
