* Disable control plane allocating podCIDR for nodes when using calico
Calico does not use the .spec.podCIDR field for its IP address
management.
Furthermore, it can false positives from the kube controller manager if
kube_network_node_prefix and calico_pool_blocksize are unaligned, which
is the case with the default shipped by kubespray.
If the subnets obtained from using kube_network_node_prefix are bigger,
this would result at some point in the control plane thinking it does
not have subnets left for a new node, while calico will work without
problems.
Explicitely set a default value of false for calico_ipam_host_local to
facilitate its use in templates.
* Don't default to kube_network_node_prefix for calico_pool_blocksize
They have different semantics: kube_network_node_prefix is intended to
be the size of the subnet for all pods on a node, while there can be
more than on calico block of the specified size (they are allocated on
demand).
Besides, this commit does not actually change anything, because the
current code is buggy: we don't ever default to
kube_network_node_prefix, since the variable is defined in the role
defaults.
* Mask systemd swap.target do disable swap
This is a more generic way to disable swap, since it pulls .swap units
in systemd distributions; fstab is only one way to generate .swap units.
* Unconditionally disable swap
We only care to disable it (the "swapon" registered variable is not used
anywhere else.
This allows to get rid of the ignore_errors, since this was added
because swapon.stdout does not exist in check_mode (see issue #6642).
* Don't explicitly disable swapOnZram
We're already masking the swap.target, which would pull the zram unit,
hence no need to handle zram-generator specifically.
* 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
* 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

* netowrkmanager: do not configure dns if using systemd-resolved
We should not configure dns if we point to systemd-resolved.
Systemd-resolved is using NetworkManager to infer the upstream DNS
server so if we set NetworkManager to 127.0.0.53 it will prevent
systemd-resolved to get the correct network DNS server.
Thus if we are in this case we just don't set this setting.

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.

* node: fix default kubelet/runtime cgroups when kube_reserved is false (default)
Commit 1c4db6132d introduced a notion of
kube_reserved. This introduced a breaking change defaulting to use
kube.slice for the container_manager and the kubelet as if kube_reserved
was always enabled whereas it is disabled by default.
This commit fixes this by bringing back system.slice whenever
kube_reserved is disabled.

This commit uses a kubeadm join config to pull down cert for etcd in
workers nodes (which is needed in some circumstances, for instance with
calico or cilium).
The previous way didn't allow us to pass certain parameters which was
typically given in the config in other kubeadm invokations in Kubespray.
This made kubeadm produced some errors for some edge cases.
For example, in our deployment we don't have a default route and even
though it's only to download the certificates, kubeadm produce an error
`unable to select an IP from default routes` (these command are kubeadm
controlplane command, so kubeadm does some additional checks). This is
fixed by specifying `advertiseAddress` within the kubeadm config.

The commit 1ce2f04 tried to merge multiple SUSE OS checks including
"openSUSE Leap" and "openSUSE Tumbleweed" into a single SUSE, but
that was a perfect change.
Then the commit c16efc9 tried to fix it for "openSUSE Leap", but it
didn't take care of "openSUSE Tumbleweed".
Then this adds "openSUSE Tumbleweed" to the OS check.
