Add a default firewall rule to allow netbird traffic to be handled by the access control managers. Userspace manager behavior: - When running on Windows, a default rule is add on Windows firewall - For Linux, we are using one of the Kernel managers to add a single rule - This PR doesn't handle macOS Kernel manager behavior: - For NFtables, if there is a filter table, an INPUT rule is added - Iptables follows the previous flow if running on kernel mode. If running on userspace mode, it adds a single rule for INPUT and OUTPUT chains A new checkerFW package has been introduced to consolidate checks across route and access control managers. It supports a new environment variable to skip nftables and allow iptables tests
