feat: добавить поддержку Kubernetes Kind кластеров

- Создан новый Docker образ k8s для работы с Kind, kubectl, Helm, Istio CLI
- Добавлены команды make k8s: create, destroy, stop, start, status, config, nodes, addon, shell
- Добавлена поддержка пресетов Kubernetes в molecule/presets/k8s/
- Создан скрипт create_k8s_cluster.py для автоматического создания кластеров и установки аддонов
- Добавлена документация docs/kubernetes-kind.md
- Команды kubectl выполняются внутри контейнера k8s, не требуют локальной установки
