add dnsPolicy: ClusterFirstWithHostNet to DaemonSets with hostNetwork: true value to avoid DNSConfigFormat events (#10618)

* Clean up redondant defaulting

drain_{timeout,grace_period}_after_failure don't exist at this point, so
they always default.

* Remove useless facts

The drain_*_after_failure are never used

* Try both conntrack modules instead of checking kernel version

Depending on kernel distributor, the kernel version might not be a
correct indicator of the conntrack module use.
Instead, we check both (and use the first found).

* Use modproble.persistent rather than manual persistence

When installed as an ansible collection, roles in
ansible_play_role_names will be designated by their FQDN (i.e
'kubernetes-sigs.kubespray.<role-name>).

It means we need to check for both when checking for roles in the play.

Older versions are unsupported for a long time.

* 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.

* Use RandomizedDelaySec to spread out control certificates renewal plane

If the number of control plane node is superior to 6, using (index * 10
minutes) will fail (03:60:00 is not a valid timestamp).

Compared to just fixing the jinja expression (to use a modulo for
example), this should avoid having two control planes certificates
update node being triggered at the same time.

* Make k8s-certs-renew.timer Persistent

If the control plane happens to be offline during the scheduled
certificates renewal (node failure or anything like that), we still want
the renewal to happen.

It was not 'false', which made some tasks (e.g. using systemd-resolved
template) to effectively remove default search domains; caused DNS loop
after rebooting the node/restarting cluster, so localdns service didn't
run correctly.

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.

The blockSize attribute from Calico IPPool resources cannot be changed
once set [1]. Consequently, we use the one currently defined when
configuring the existing IPPool, avoiding upgrade errors by trying to
change it.

In particular, this can be useful when calico_pool_blocksize default
changes in kubespray, which would otherwise force users to add an
explicit setting to their inventories.
