* 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.
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.
* Decouple role kubespray-defaults from download
Avoids doing re-importing the download role on every invocation of
kubespray-defaults (and skipping everything).
This has a measurable effect on playbook performance.
* Update docs refering to moved download 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.
* 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.
* 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.

Sets ignore_unreachable: true to `Gather ansible_default_ipv4 from all hosts`
task from fallback_ips.yml
Without this scale.yml will fail if a single node in the cluster is down, which
for large clusters happens often.
Remove cri-o apt repo job has state present but need absent
Uninstall CRI-O packages job has undefined variable crio_packages
replaced by list of packages
* metallb --lb-class cmd arg to support multiple load balancer implementations
* removed loadbalancer_class from metallb_config; metallb_loadbalancer_class in role defaults
* 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.
* Specify the runc path when we use the containerd container engine
and change the bin_dir path.
