This commit introduces the Kubernetes job client and service, providing a mechanism to schedule tasks on Kubernetes clusters (including GKE and Kind), supporting both standard and Kata Containers.
Key Features & Changes:
- **Kubernetes Service**: Implemented `KubernetesService` in `clusterfuzz._internal.k8s.service` to manage job creation.
- **Kata Support**: Added specialized job creation for Kata Containers (`create_kata_container_job`) with required security context (`privileged`, `capabilities: ALL`), networking (`hostNetwork: True`), and environment variables (`HOST_UID`).
- **Dependency Management**: Added `kubernetes` and necessary Google Cloud dependencies (`google-api-python-client`, `google-cloud-storage`, `google-cloud-ndb`, etc.) to `Pipfile`.
- **E2E Testing**:
- Created `tests.core.k8s.k8s_service_e2e_test` to verify job lifecycle on a local Kind cluster.
- Updated `local/tests/kubernetes_e2e_test.bash` to provision the test environment.
- Updated CI workflow (`.github/workflows/kubernetes-e2e-tests.yaml`) to install JDK 21 (required for Datastore emulator).
- Tests now verify job "Running" status to avoid timeouts with long-running commands.
- `KubernetesService` skips default credential loading when `K8S_E2E` is set to utilize the test-provided kubeconfig.
- **Unit Tests**: Added comprehensive unit tests in `tests.core.k8s.k8s_service_test` and `tests.core.kubernetes.kubernetes_test`, including mocking of `load_kube_config` and `_load_gke_credentials` to ensure robust testing without external dependencies.
