Run tasks by node attributes specific parameters

[ljluestc]

• Add attribute-based node selection to KubeMarine for both CLI tasks and upgrade procedures.
• Issue / motivation (Run tasks by node attributes specific parameters – Run tasks by node attributes specific parameters #419):
  • KubeMarine previously could only target nodes by explicit name in both task flows and upgrade procedures.
  • This made it difficult to operate on label‑ or role‑driven topologies, for example:
    • “All workers in region=infra”
    • “All infra nodes in a specific zone”
  • The same subsets of nodes had to be duplicated by name across inventories and procedure YAMLs, increasing maintenance cost and risk of drift.
  • The desired behavior from Run tasks by node attributes specific parameters #419 is:
    • Procedure example:

      upgrade_plan:
        - v1.26.3
      
      upgrade_nodes:
        labels: { region: infra }

    • CLI example:

      kubemarine install --tasks="prepare.package_manager" --nodes="labels='region=infra'"

• This change introduces:
  • A --nodes selector flag for task-based CLI flows.
  • Selector objects (labels, roles) for upgrade_nodes in the procedure inventory.
  • Centralized node-group filtering in KubernetesCluster, so existing tasks automatically gain selector support without per-task changes.

Fixes #419
