agent has built-in items to return mac/hw addresses and interfaces on a system, but there is no way to get a list of ip addresses.

this would be useful when one would like to test all ip addresses for some open port, or to determine internal ip address of an auto-registered host behind nat.

a couple of different items could be of use - one that returns plain list of the addresses (like mac address one does), and another that returns ip addresses in lld json structure (allowing to filter out 127.0.0.1 etc)
