Migrate examples to tests_e2e directory structure

- Relocated all files and scripts from `examples` to `tests_e2e` for better organization.
- Updated references and paths in configurations, scripts, and test files.
- Adjusted `bump-version.sh` to handle the new `tests_e2e` structure.
- Updated `.gitignore` to reflect path changes.

+# ==============================================================================
+# EXAMPLE: IP Whitelist Plugin for Kubernetes
+# ==============================================================================
+#
+# WHAT THIS DEMONSTRATES:
+# - Restricting access to specific IP addresses or CIDR ranges
+# - Using annotations for IP-based access control
+# - Protecting admin panels or sensitive services in Kubernetes
+# - Custom HTTP status code for blocked requests
+#
+# REQUIREMENTS (run these first):
+# ```bash
+# # 1. Ensure EasyHAProxy is installed in your cluster
+# kubectl create namespace easyhaproxy
+# kubectl apply -f https://raw.githubusercontent.com/byjg/docker-easy-haproxy/5.0.0/deploy/kubernetes/easyhaproxy-daemonset.yml
+#
+# # 2. IMPORTANT: Edit this file (line 80) and update allowed_ips
+# #    with your actual office/VPN IP addresses or networks
+# ```
+#
+# HOW TO START:
+# ```bash
+# kubectl apply -f ip-whitelist.yml
+# ```
+#
+# HOW TO VERIFY IT'S WORKING:
+# ```bash
+# # Check resources are created
+# kubectl get deployment,service,ingress -l app=admin
+#
+# # Test from allowed IP
+# kubectl port-forward -n easyhaproxy deployment/easyhaproxy 8080:80
+# curl -H "Host: admin.example.local" http://localhost:8080
+# # Expected: 200 OK with "Admin Panel - IP Restricted" (if your IP is in allowed_ips)
+#
+# # Test from non-allowed IP
+# # Expected: HTTP 403 Forbidden
+# ```
+#
+# CLEAN UP:
+# ```bash
+# kubectl delete -f ip-whitelist.yml
+# ```
+#
+# ==============================================================================
