This commit adds a new file `meta/fail2ban.md` containing detailed documentation on how to deploy and configure Fail2Ban on Proxmox VE, including integration with the Proxmox firewall. The documentation aims to provide comprehensive guidance for users looking to enhance their server security by implementing Fail2Ban.
This refactoring includes updating the README, changing the role name to focus on Proxmox VE, enhancing compatibility matrix, and refactoring default values for role variables. Handlers are updated to manage apt cache, restart pveproxy, and reload systemd. Role metadata is also updated for better Proxmox VE provisioning.
