Services updates (LoadBalancerConfig and NodePortConfig) (#329)

* updates to services

- added loadBalancerConfig
- removed service-port
- added logic to not expose services

* Refactor cluster tests to improve readability and maintainability

- Simplified service port expectations by directly accessing elements instead of using `ContainElement`.
- Enhanced clarity of test assertions for `k3s-server-port` and `k3s-etcd-port` attributes.
- Removed redundant code for checking service ports.

* fix ports for ingress expose, update kubeconfig generate
