This change was necessary, because the configuration was always
generated with a gRPC TLS port, which did not exist in Consul 1.13,
and would result in the server failing to launch with an error.
This code checks the version of Consul and conditionally adds the
gRPC TLS port, only if the version number is greater than 1.14.
* Add new consul connect redirect-traffic command for applying traffic redirection rules when Transparent Proxy is enabled.
* Add new iptables package for applying traffic redirection rules with iptables.
