This PR introduces a new diagnostic runbook for Dataproc within `gcpdiag`. The `NetworkingRunbook` aims to help users troubleshoot common networking and permission issues that can affect Dataproc cluster creation and operation.
**Key Changes:**
* **New Runbook:** `dataproc/networking_runbook.py` orchestrates a series of checks.
* **Individual Check Modules:** Added new rule modules under `gcpdiag/runbook/dataproc/` for specific checks:
* `cluster_existence.py`: Verifies the cluster exists.
* `private_google_access.py`: Checks if Private Google Access is enabled on the cluster's subnet.
* `cloud_nat.py`: Checks if Cloud NAT is configured for the subnet if needed.
* `firewall.py`: Looks for overly restrictive egress firewall rules (e.g., deny all to 0.0.0.0/0).
* `security_and_iam.py`: Placeholder for IAM and Service Account permission checks.
* `cloud_vpn_and_interconnect.py`: Placeholder for Cloud VPN / Interconnect checks.
* `dns.py`: Placeholder for DNS configuration checks.
* `private_service_connect.py`: Placeholder for Private Service Connect checks.
* `secure_web_proxy.py`: Placeholder for Secure Web Proxy checks.
* `service_accounts.py`: Placeholder for detailed Service Account checks.
* `vpc_peering.py`: Placeholder for VPC Peering checks.
* `vpc_service_controls.py`: Placeholder for VPC Service Controls checks.
* **Unit Tests:** Each new rule module includes a corresponding test file (e.g., `cloud_nat_test.py`).
* **Reporting Template:** Added `templates/networking.jinja` to format the output of the runbook.
**Details:**
The runbook executes checks in a logical order. Currently, `Private Google Access`, `Cloud NAT`, and `Firewall` checks have initial implementations. Other modules (IAM, DNS, VPC features, etc.) are placeholders and will be fully implemented in subsequent PRs.
This runbook structure allows for modular and extensible network diagnostics for Dataproc.
