The `containerd-common` role is responsible for gathering OS specific variables from the vars directory of the roles that include or import it. `containerd-common` is imported via role dependency by a total of two roles, `container-engine/docker`, and `container-engine/containerd`.
containerd-common is needed by both the docker and containerd roles as a dependency when:
- containerd is selected as the container engine
- a docker install is detected and needs to be removed
- apt is the package manager
However, by default, roles can not be invoked more than once in the same play, unless `allow_duplicates: true` is set for that role. This results in the failure of the `containerd | Remove containerd repository` task, since only the docker vars will be loaded in the play, and `containerd_repo_info.repos`, normally populated by containerd/vars, is left empty.
This change sets `allow_duplicates: true` for `containerd-common` which fixes the currently failing containerd tasks if docker was detected and removed in the same play.
by setting a default runtime spec with a patch for RLIMIT_NOFILE.
- Introduces containerd_base_runtime_spec_rlimit_nofile.
- Generates base_runtime_spec on-the-fly, to use the containerd version
of the node.
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.
* Force containerd service unmasking
Force systemd to unmask and start service when adding containerd service
* Eliminate restart and move unmasking step
Switch to start instead of restart
Move unmasking to restart handler
* Add unmasking to similar container runtimes
* Add missing service names
