- Remove gpc2 from stick-table (not supported in HAProxy 3.0)
- Fix ACL syntax: Change sc_get_gpc0(0) to sc0_get_gpc0
- Fix ACL syntax: Change sc_http_err_rate(0,period) to sc0_http_err_rate(period)
- Fix ACL syntax: Change sc_get_gpc1(0) to sc0_get_gpc1
- Reorder rules to place http-request rules before use_backend rules
- Remove duplicate gpc2 increment rule
These changes ensure compatibility with HAProxy 3.0.11 while maintaining
the tarpit escalation functionality for exploit scanning protection.

Implement progressive tarpit delays and threat detection to slow down
attackers scanning for exploits. Features include:
- Stick table to track attacks with 2-hour expiry
- Escalating tarpit delays based on threat level and repeat offenses
- Threat level detection (low/medium/high/critical) based on scan attempts
- Rate-based attack detection for burst/sustained/persistent attacks
- Automatic scan attempt tracking via HTTP error responses (400/401/403/404)
- Detection of suspicious paths (admin panels, config files, etc.)
- Trusted network bypass for local/monitoring systems
- Progressive escalation levels that increase tarpit duration
- Critical threat blocking with 429 status
The system uses HAProxy's built-in tarpit mechanism to delay responses
up to 60 seconds for persistent attackers, effectively slowing down
vulnerability scanners while maintaining service for legitimate users.
