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
This fixes the Containerd + EL8 case that was missed in 7d1ab3374e
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.

* Add docker-ce 19.03 packages for Debian & Ubuntu
K8s has updated the recommended Docker version to 19.03. More
specifically it should be 19.03.4, but since we used 18.06.7 instead of
.2, I'm assuming the latest patch version should be used here as well.
* Add docker 19.03 for redhat
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

When docker_container_storage_setup is false,
docker service should not depend on docker-storage-setup service,
because it's not installed.
For example, when using overlay2 on recent RHEL 7/Centos 7 kernels,
you most likely don't need it.
We don't need to support upgrades from 2 year old installs,
just from the last major version.
Also changed most retried tasks to 1s delay instead of longer.
* 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.
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.
The containerd service and socket files have been dropped from the
openSUSE docker package so we should not require them in the docker
service anymore. This makes the docker service file look similar to
the one shipped by the openSUSE package.
