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: Cloudflare IP Restoration (Swarm)
+# ==============================================================================
+#
+# WHAT THIS DEMONSTRATES:
+# - Restoring original visitor IPs when behind Cloudflare CDN
+# - Using Docker configs to manage Cloudflare IP lists
+# - Service discovery in Swarm mode with plugins
+# - Load balancing across multiple replicas
+#
+# REQUIREMENTS (run these first):
+# ```bash
+# # Initialize Docker Swarm (if not already initialized)
+# docker swarm init
+#
+# # Create overlay network (idempotent)
+# docker network ls | grep -q easyhaproxy || docker network create --driver overlay --attachable easyhaproxy
+#
+# # Ensure EasyHAProxy is deployed
+# docker stack deploy -c easyhaproxy.yml easyhaproxy
+#
+# # Download Cloudflare IP ranges and create Docker config
+# curl https://www.cloudflare.com/ips-v4 > cloudflare_ips.lst
+# echo "" >> cloudflare_ips.lst
+# curl https://www.cloudflare.com/ips-v6 >> cloudflare_ips.lst
+# docker config create cloudflare_ips cloudflare_ips.lst
+# rm cloudflare_ips.lst
+#
+# # Add to /etc/hosts for local testing (idempotent)
+# grep -q "myapp.example.com" /etc/hosts || echo "127.0.0.1 myapp.example.com" | sudo tee -a /etc/hosts
+# ```
+#
+# HOW TO START:
+# ```bash
+# docker stack deploy -c cloudflare.yml webapp
+# ```
+#
+# HOW TO VERIFY IT'S WORKING:
+# ```bash
+# # Check stack is deployed
+# docker stack ls | grep webapp
+# # Expected: webapp stack listed
+#
+# # Check service is running
+# docker service ls | grep webapp_webapp
+# # Expected: webapp_webapp with 4/4 replicas
+#
+# # Test the application
+# curl -H "Host: myapp.example.com" http://localhost/
+# # Expected: 200 OK with "App Behind Cloudflare"
+#
+# # Check HAProxy config includes Cloudflare IPs
+# docker exec $(docker ps -q -f name=easyhaproxy_haproxy) cat /etc/haproxy/haproxy.cfg | grep -A 5 "cloudflare"
+# # Expected: ACL rules for Cloudflare IP ranges
+# ```
+#
+# CLEAN UP:
+# ```bash
+# docker stack rm webapp
+# # To also remove the Cloudflare IPs config:
+# # docker config rm cloudflare_ips
+# ```
+#
+# NOTE: This plugin is most useful when your site is actually behind Cloudflare CDN.
+# The plugin uses the CF-Connecting-IP header to restore the original visitor IP.
