Use the new firewall code vendored from CNI to replace the existing iptables rule addition handler we had in place. This adds proper support for firewalld and should be much better at interacting with the firewall. Signed-off-by: Matthew Heon <matthew.heon@gmail.com> Closes: #1431 Approved by: baude
