Since we're not longer injecting pseudo DNS into /etc/hosts,
'lb-apiserver.kubernetes.local' (the previous default) won't resolve to
anything.
Instead, default to the loadbalancer IP if defined, or to the node local
loadbalancer if it's in use.
Make the necessary adjustements in use site to deal with ip addresses as
well as hostnames.
- invoke setup module only once to gather ipv4 and ipv6 addresses
- eliminate remaining use of `fallback_ip` and `fallback_ip6`, allowing
us to define (with `set_fact` all the "computed" IPs variable in one
go, since there is no longer a dependency between them.
Before "5ca23e3bf (Changed to use first_kube_control_plane to parse
kubeadm_certificate_key (#11875), 2025-01-14)", kubespray would have
problem adding new control planes when the order of the nodes in kubectl
output and the ansible inventory were not the same.
But the underlying problem is that the operation is fundamentally
something that should be done only once, and recorded for all host in
play.
Since `register` and `sef_fact` when used with `run_once` set the
variable for all the hosts, use it. Also allows to use the variable
directly instead of relying on hostvars to make the task more readable.
Most variables should have a default instead of relying on the default
filter.
(Note that the variable is misnomed, this should be certs and not keys,
but it's not worth breaking compat).
* control-plane: fix first_kube_control_plane delegation with kube_override_hostname
When kube_override_hostname is configured, the node names reported by
`kubectl get nodes` differ from the inventory_hostname known to Ansible.
This causes delegation failures in subsequent tasks since Ansible cannot
resolve the hostname from kubectl output to an inventory host.

* control-plane: remove fragile first_control_plane selection logic
Current implementation breaks with kube_override_hostname and has
multiple edge cases. Drop until proper kubectl-based node lookup
can be implemented.

Fixes a bug where `kube-apiserver` fails to start if the PodSecurity

Retrying to load conntrack modules was bound to fail due to the way, the current `when` conditions were utilized.
It was based on the assumption, that in case of success, the registered variable would have an `rc` attribute with the value `0`.
Unfortunately, the `rc` attribute is only present in case of a failure, where it's value is >1.
The result of `community.general.modprobe` in case of success looks like this:
```
{
"changed": false,
"msg": "All items completed",
"results": [
{
"ansible_loop_var": "item",
"changed": false,
"failed": false,
"invocation": {
"module_args": {
"name": "nf_conntrack",
"params": "",
"persistent": "present",
"state": "present"
}
},
"item": "nf_conntrack",
"name": "nf_conntrack",
"params": "",
"state": "present"
}
],
"skipped": false
}
```
While it looks like this in case of a failure:
```
{
"changed": false,
"failed": true,
"msg": "One or more items failed",
"results": [
{
"ansible_loop_var": "item",
"attempts": 3,
"changed": false,
"failed": true,
"invocation": {
"module_args": {
"name": "nf_conntrack_doesnotexist",
"params": "",
"persistent": "present",
"state": "present"
}
},
"item": "nf_conntrack_doesnotexist",
"msg": "modprobe: FATAL: Module nf_conntrack_doesnotexist not found in directory /lib/modules/5.14.0-570.32.1.el9_6.x86_64\n",
"name": "nf_conntrack_doesnotexist",
"params": "",
"rc": 1,
"state": "present",
"stderr": "modprobe: FATAL: Module nf_conntrack_doesnotexist not found in directory /lib/modules/5.14.0-570.32.1.el9_6.x86_64\n",
"stderr_lines": [
"modprobe: FATAL: Module nf_conntrack_doesnotexist not found in directory /lib/modules/5.14.0-570.32.1.el9_6.x86_64"
],
"stdout": "",
"stdout_lines": []
}
],
"skipped": false
}
```
By evaluating `failed` instead, this issue can be prevented.
