If callers of get_devices_with_ip(), or
device.addr.list(to=address) pass an ip_cidr, it
could match any ip_cidr in that range on the interface.
Callers need to pass the IP without the prefix portion in
order to match it exactly. Added a helper utility to
strip the cidr part from a ip_cidr.
Determined the unit test for this can't actually check
this case since we are mocking the return value from
/sbin/ip, so modified it to just make sure the dict
is correct.
Added a functional test that adds two IP addresses in
the same IP range to verify that we actually filter
correctly when a 'to=IP' is specified.
