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

serving therefore, there is a need to migrate to the new one.

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.

Add support for installing kubernetes cluster via devstack.
It uses kubeadm to bootstrap the k8s cluster.
Change-Id: I7877ceda08bbdab807116a13d74ff884136dc501
ENABLE_CLEAR_CONTAINER should be set to false by default as they're
relying on third party repos which could break devstack installation at
some point.

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.
