Refactor NRI (Node Resource Interface) activation in CRI-O and
containerd. Introduce a shared variable, nri_enabled, to streamline
the process. Currently, enabling NRI requires a separate update of
defaults for each container runtime independently, without any
verification of NRI support for the specific version of containerd
or CRI-O in use.
With this commit, the previous approach is replaced. Now, a single
variable, nri_enabled, handles this functionality. Also, this commit
separates the responsibility of verifying NRI supported versions of
containerd and CRI-O from cluster administrators, and leaves it to
Ansible.

* [containerd] Add Configuration option for Node Resource Interface
Node Resource Interface (NRI) is a common is a common framework for
plugging domain or vendor-specific custom logic into container
runtime like containerd. With this commit, we introduce the
containerd_disable_nri configuration flag, providing cluster
administrators the flexibility to opt in or out (defaulted to 'out')
of this feature in containerd. In line with containerd's default
configuration, NRI is disabled by default in this containerd role
defaults.

* [cri-o] Add configuration option for Node Resource Interface
Node Resource Interface (NRI) is a common is a common framework for
plugging domain or vendor-specific custom logic into container
runtimes like containerd/crio. With this commit, we introduce the
crio_enable_nri configuration flag, providing cluster
administrators the flexibility to opt in or out (defaulted to 'out')
of this feature in cri-o runtime. In line with crio's default
configuration, NRI is disabled by default in this cri-o role

- Test with new version: 37.20230322.3.0. Both containerd and
cri-o is tested
- bugfix: when we use crio and the var bin_dir is changed,
there will be some error about the new bin dir.
* optimize cgroups settings for node reserved
* fix
* set cgroup slice for multi container engine
* set cgroup slice for crio
* add reserved cgroups variables to sample files
* Compatible with cgroup path for different container managers
* add cgroups doc
* fix markdown
When privileged is enabled for a container, all the `/dev/*` block
devices from the host are mounted into the guest. The
`privileged_without_host_devices` flag prevents host devices from
being passed to privileged containers.

* Enable Kata Containers for CRI-O runtime
Kata Containers is an OCI runtime where containers are run inside
lightweight VMs. This runtime has been enabled for containerd runtime
thru the kata_containers_enabled variable. This change enables Kata
Containers to CRI-O container runtime.

After host reboot kubelet and crio goes into a loop and no container is started.
storage_driver in crio.conf overrides system defaults in etc/containers/storage.conf
/etc/containers/storage.conf is installed by package containers-common dependency
installed from cri-o (centos7) and contains "overlay".
Hosts already configured with overlay2 should be reconfigured and the
/var/lib/containers content removed.
By default do not allow "unqualified" (without a registry) images
because it is considered unsecure and subject to mitm attacks.
To enable insecure pull configure for example:
crio_registries:
- "docker.io"
- "quay.io"
* log level by default increased to 'info'
* cgroup manager by default set to 'systemd'
* stream port (used by kubelet) bound to 127.0.0.1 for security reasons
* metrics can be enabled and port specified

- update documents
* install conntrack required by kube-proxy

The BINDIR variable defined on the runc's Makefile[1] defines
installation path is on $(PREFIX)/sbin which used for most of the
Linux distributions. This change fixes the absolute path used for
non-ClearLinux distributions (CentOS, Ubuntu).
