Add/delete deterministic NAT mapping.

Create bijective mapping of inside address to outside address and port range pairs, with the purpose of enabling deterministic NAT to reduce logging in CGN deployments.

Parameters
in_addrInside network address.
in_plenInside network prefix length.
out_addrOutside network address.
out_plenOutside network prefix length.
is_addIf 0 delete, otherwise add.
