change nodeSelector label from deprecated beta.kubernetes.io/os and arch to kubernetes.io prefix (#7138)

TASK [Generate a list of information about the images on a node]
registers list of container images to docker_images.
Then the next TASK [Set pull_required if the desired image is not
yet loaded] does based on expecting images are registered.
However sometimes the first TASK was failed as [1] but the failure
is ignored due to failed_when:false and it makes another issue.
This removes this unnecessary failed_when to detect the failure
at the point.
In addition, this removes no_log:true also because the output doesn't
contain any sensitive data and now it just makes debugging difficult.

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

In some environments, it might not be possible to ping the IP address
of the nodes, e.g., because ICMP echo is blocked.

This commit allows kubespray to be configured to disable the ping
check, while performing all other checks.

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
