Support multiple address resolution in DNS requests

Browse source 
Add two new functions to the IP class that returns all addresses/aliases associated with a given address.

This is a cherry-pick merge from 010a3433df43a94fee95474360ffa6662c7441b9 which was merged in 2.1, and has been updated to build with the latest code.

This merge adds two new methods IP.resolve_hostname_addresses and IP.get_resolve_item_addresses that returns a List of all addresses returned from the DNS request.
