The default behavior of crio service is `disable` if you install it with
devstack. So, kubelet cannot launch after rebooting a host because crio
isn't run on the host before. To fix the issue, enable crio in systemctl
while installing kubeadm.

Kubernetes 1.19 is long gone over a year now. Current minimal supported
version is 1.23.x. It is also last version, which supports docker-shim.
In this patch we propose to bump the version of k8s to 1.23.16 and crio
to 1.23.

Last year, kubernetes community has made a move from k8s.gcr.io to
registry.k8s.io. Currently images on k8s.gcr.io has been stopped from
serving therefore, there is a need to migrate to the new one.

Recently there are failures observed with docker installations. Newest
version (23.x) started to fail to create containers, when there are no
tools for apparmor available, and yet, this feature is enabled on
kernel, which is true in case of Ubuntu Jammy (22.04) stable release.
There are couple[1] of bugs[2] reported to the upstream, and as a
workaround, proposal is to install apparmor.

In earlier version of cri-o (at least that been seen in 1.18) cri-o
packages have default configuration stored as /etc/crio/crio.conf, with
all the default values defined. Setting a value for the key means that
was a need to actually change the default. In version up to 1.23 there
was even no configuration stored at all, but starting from 1.24, all the
default config options has been commented out, and only section names
are not commented.
Similar situation has been detected for registry configuration, but here
it is even more difficult, as in recent version toml format has been
used instead of ini.
With this patch all of the cases has been covered.

In some places of which network environment was limited, ciro can't
pull images from k8s.gcr.io. This patch add a variable
`CRIO_PAUSE_IMAGE` in order to the developer who located in these
places can set the ciro to pull pause container images from
repository that they can access.
The `CRIO_PAUSE_COMMAND` used to configure crio's `pause_command`
(the pause container's bootstrap command), in order to the developer
can use the special pause image the they customized.

By default, CRI-O doesn't allow to have ICMP traffic between the pods
and pods to/from host. It's convenient to have such ability for testing
and debugging purpose.
In this patch there is added appropriate configuration to crio.conf, and
also a setting to disable it if needed.

There are also two new configuration option introduced:
- CNI_PLUGIN_DIR
- CNI_CONF_DIR
which, if defined, are used to configure crio paths for plugins and
networks config.

Since projectatomic Ubuntu builds are deprecated, and advice was to
consult upstream documentation[1], Kubernetes with cri-o now rely on
Kubic project, which (among the others) provides packages for Ubuntu
20.04. Let us switch for those.

There are several projects that tried to install docker in different
ways. This potentially lead to failure of more than one such services
were enabled. This commit consolidate docker installation into
a devstack plugin so that other services could depend on it.
The initial script was mainly from Kuryr-libnetwork. Kuryr, Fuxi,
and Zun might leverage this script to install Docker in the future.
