[dualtor-aa] add test to verify iptables nat rules for mux port (#14919)
Covers test gap #11436 which is raised to cover this issue sonic-net/sonic-host-services#95. The test will check nat rules and make sure vlan ip to mux cable soc_ip snat is correct, and in the case of multivlan, only vlan ip of the vlan as soc_ip is used.
