When we saw 0 as the default value of containerd_oom_score, we had
a question why the value was not -999.
This adds the note to explain it.

To block merging pull requests which contain typo automatically.

The ostree variable is not defined previously raising an error when
the runtime tries to read it.

and supply a default runtime spec.

* cri-dockerd: add restart of docker.service

* remove enabling of cri-dockerd.socket

For the following configuration

```
    containerd_insecure_registries:
      docker.io:
        - dockerhubcache.example.com
```

the rendered /etc/containerd/config.toml contains

```
        [plugins."io.containerd.grpc.v1.cri".registry.configs."docker.io".tls]
          insecure_skip_verify = true
```

but it needs to be

```
        [plugins."io.containerd.grpc.v1.cri".registry.configs."dockerhubcache.example.com".tls]
          insecure_skip_verify = true
```

When running molecule jobs, we saw the folloing warning message:

 [DEPRECATION WARNING]: [defaults]callback_whitelist option, normalizing names
 to new standard, use callbacks_enabled instead. This feature will be removed
 from ansible-core in version 2.15. Deprecation warnings can be disabled by
 setting deprecation_warnings=False in ansible.cfg.

callbacks_enabled has been added since Ansible 2.11 and Kubespray is using
Ansible 2.12 at master branch. So we can use callbacks_enabled safely to
avoid the warning message.
