Example Configurations and Use Cases

**Difficulty:** ⭐ (Easy)
**Dependencies:** Issue #2
**Component:** Documentation

**Description:**
Develop a comprehensive collection of example configurations and real-world use case scenarios that demonstrate Knetz capabilities in practical situations. This includes basic single-cluster setups for getting started quickly, complex multi-tenant configurations showing how large organizations can manage multiple business units, cross-cluster dependency scenarios demonstrating how to handle services that depend on services in other clusters, and GitOps integration examples showing how to use Knetz in CI/CD pipelines. Each example should include the complete configuration file, expected output, and explanations of why specific settings were chosen. Add troubleshooting scenarios for common problems users might encounter, and create a best practices guide based on lessons learned from production deployments.

**Acceptance Criteria:**
- [ ] Add basic setup examples
- [ ] Create multi-tenant examples
- [ ] Add cross-cluster scenarios
- [ ] Implement GitOps integration examples
- [ ] Add troubleshooting scenarios
- [ ] Create best practices guide

**Why Early:** Provides practical guidance for testing and validation.

The payload names no documentation files or tests; resolve dependency #2 first and locate Knetz's existing configuration and documentation structure. Add the requested basic, multi-tenant, cross-cluster, GitOps, troubleshooting, and best-practices examples, with complete configurations, expected output, and explanations for every acceptance criterion.
