Add qos_* iptables chain namespace for QoS
Prefix the names of the iptables chains used for QoS with "qos_" to
allow for identification of QoS chains for removal across configuration
changes. When clearing QoS iptables chains, only remove chains with the
namespace prefix in order to preserve user and/or other package chains
in the mangle table.
