* etcd: throttle restart for availability
During upgrade, etcd member are restarted all at once.
This can impact the availability of the etcd cluster and subsequently of
the Kubernetes cluster.
Limit the concurrent restart so that the etcd cluster can keep quorum.
* Simplify etcd handlers
The fallback_ips tasks are essentially serializing the gathering of one
fact on all the hosts, which can have dramatic performance implications
on large clusters (several minutes).
This is essentially a reversal of 35f248dff0ddb430e2293af98ba73aa5062c89c1
Being able to run without refreshing the cache facts is not worth it.
We keep fallback_ip for now, simply changing the access to a normal
hostvars variable instead of a custom dictionnary.
Testing for group membership with group names makes Kubespray more
tolerant towards the structure of the inventory.
Where 'inventory_hostname in groups["some_group"] would fail if
"some_group" is not defined, '"some_group" in group_names' would not.
We take advantage of group_by to create the list of nodes needing new
certs, instead of manually looping inside a Jinja template.
This should make the role more readable and less susceptible to
white space problems.
* Validate systemd unit files
This ensure that we fail early if we have a bad systemd unit file
(syntax error, using a version not available in the local version, etc)
* Hack to check systemd version for service files validation
factory-reset.target was introduced in system 250, same version as the
aliasing feature we need for verifying systemd services with ansible.
So we only actually executes the validation if that target is present.
This is an horrible hack which should be reverted as soon as we drop
support for distributions with systemd<250.
* containerd: refactor handlers to use 'listen'
* cri-dockerd: refactor handlers to use 'listen'
* cri-o: refactor handlers to use 'listen'
* docker: refactor handlers to use 'listen'
* etcd: refactor handlers to use 'listen'
* control-plane: refactor handlers to use 'listen'
* kubeadm: refactor handlers to use 'listen'

* preinstall: refactor handlers to use 'listen'
* calico: refactor handlers to use 'listen'
* kube-router: refactor handlers to use 'listen'
* macvlan: refactor handlers to use 'listen'
This make native ansible features (dry-run, changed state) easier to
have, and should have a minimal performance impact, since it only runs
on the etcd members.
This allows this task to work with a forks count > 10 and the default
configuration of sshd, which is to limit sessions to 10. (see
MaxSessions in sshd_config).
Since this is a delegate_to task, it connects to the same host (first
etcd) for each node in the cluster, thus easily going above 10.
Raising the ssh connection attempts allow for more robustness, without
decreasing the forks count or serialising the tasks, which could slow
the task (or the playbook as a whole, if decreasing forks).

According to the canal github[1] the repo is not maintained over 5 years.
In addition, the README says
```
Originally, we thought we might more deeply integrate the two projects
(possibly even going as far as a rebranding!). However, over time it
became clear that that wasn't really necessary to fulfil our goal of
making them work well together. Ultimately, we decided to focus on
adding features to both projects rather than doing work just to
combine them.
```
So it is difficult to support canal by Kubespray at this situation.
