refactor: extract DNS configuration from kubernetes/preinstall into dns_config role (#13603)

Browse Source 
Extract tasks related to host DNS management from kubernetes/preinstall
into a new kubernetes/dns_config role.

Previously, kubernetes/preinstall was re-invoked at the end of cluster
playbooks with dns_late: true to apply resolvconf changes after cluster
DNS came up. Because of this reuse, several unrelated tasks in preinstall
were guarded with 'when: not dns_late'.

Move resolvconf, systemd-resolved, networkmanager-dns, and dhclient tasks,
along with their associated templates, facts, variables, and handlers, into
kubernetes/dns_config. Update cluster.yml, upgrade_cluster.yml, scale.yml,
and reset.yml to invoke the new role directly and remove dns_late guards.
