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: Let's Encrypt SSL with ACME/Certbot
+# ==============================================================================
+#
+# WHAT THIS DEMONSTRATES:
+# - Automatic SSL certificate generation using Let's Encrypt
+# - HTTP-01 ACME challenge protocol
+# - Certificate persistence across container restarts
+# - Auto-renewal of certificates
+#
+# REQUIREMENTS (run these first):
+# ```bash
+# # You MUST have:
+# # - A public IP address pointing to your machine
+# # - Ports 80 and 443 open in your firewall
+# # - A valid domain name with DNS configured
+#
+# # Edit this file and change:
+# # - Line 21: EASYHAPROXY_CERTBOT_EMAIL to your email
+# # - Line 36: easyhaproxy.http.host to your real domain
+#
+# # Create certs directory
+# mkdir -p ./certs/certbot
+# ```
+#
+# HOW TO START:
+# ```bash
+# docker compose -f docker-compose-acme.yml up -d
+# ```
+#
+# HOW TO VERIFY IT'S WORKING:
+# ```bash
+# # Check logs for certificate issuance
+# docker compose -f docker-compose-acme.yml logs -f haproxy
+# # Look for: "Successfully received certificate"
+#
+# # Test HTTPS with real domain (replace test.xpto.us with your domain)
+# curl https://test.xpto.us/
+# # Expected: 200 OK with valid SSL certificate
+#
+# # Verify certificate
+# openssl s_client -showcerts -connect test.xpto.us:443 < /dev/null | grep "Issuer:"
+# # Expected: Issuer: C = US, O = Let's Encrypt
+#
+# # Check certificate files
+# ls -la ./certs/certbot/
+# # Expected: Your domain certificate files
+# ```
+#
+# CLEAN UP:
+# ```bash
+# docker compose -f docker-compose-acme.yml down
+# # Keep certificates:
+# # docker compose -f docker-compose-acme.yml down
+# # Remove certificates too:
+# # docker compose -f docker-compose-acme.yml down && rm -rf ./certs/certbot
+# ```
