It seems that PR #8839 broke `calico_datastore: etcd` when it removed ipamconfig support for etcd mode.

This PR fixes some failing tasks when `calico_datastore == etcd`, but it does not restore ipamconfig support for calico in etcd mode. If someone wants to restore ipamconfig support for `calico_datastore: etcd` please submit a follow up PR for that.

* 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
```

* 🌱 Enable cri-dockerd service

* 🔨 Fix the task name in order to pass the CI tests

See #9035

* Add the option to enable default Pod Security Configuration

Enable Pod Security in all namespaces by default with the option to
exempt some namespaces. Without the change only namespaces explicitly
configured will receive the admission plugin treatment.

* Fix the PR according to code review comments

* Revert the latest changes

- leave the empty file when kube_pod_security_use_default, but add comment explaining the empty file
- don't attempt magic at conditionally adding PodSecurity to kube_apiserver_admission_plugins_needs_configuration

* Add 'flush ip6tables' task in reset role 

If enable_dual_stack_networks is set to true and ip6 is defined，ip6tables will be created. But when reset the kubernetes cluster, kubespray doesn't flush ip6tables.
