[busma13]

This PR makes the following changes:

• Creates a kubernetesV2 directory under packages/teraslice/src/lib/cluster/services/cluster/backends with copies of all files in kubernetes directory
• Modify K8s class to use @kubernetes/client-node instead of kubernetes-client
• Modify index.ts:
  • Rename class KubernetesClusterBackendV2
  • Account for typed responses from new client
• Account for kubernetesV2 possibility anywhere cluster_manager_type, CLUSTERING_TYPE or TEST_PLATFORM are checked
• Duplicate unit tests related to k8s to run k8sV2 also
• Add e2e-k8s-v2-tests to github workflow
• Update ts-scripts test and ts-scripts k8s-env to allow for kubernetesV2 clustering
• Add clustering-type and keep-open flags to ts-scripts k8s-env
• Add k8sV2 script to root package.json
• Add @terascope/types:0.17.2 as scripts dependency

Set cluster_manager_type to kubernetesV2 in your terafoundation config:

terafoundation:
    ...
teraslice:
    ...
    cluster_manager_type: kubernetesV2
    ...

Check the clustering_type to verify kubernetesV2 backend:

curl localhost:5678
{
    "arch": "arm64",
    "clustering_type": "kubernetesV2",
    "name": "ts-dev1",
    "node_version": "v18.19.1",
    "platform": "linux",
    "teraslice_version": "v1.6.1"
