Add support of args and kwargs in call_until_true

Now call_until_true doesn't accept args and kwargs,
so if want to call a callable with parameters, we have to
do like this(test_network_v6.py):
    srv1_v6_addr_assigned = functools.partial(
        guest_has_address, sshv4_1, ips_from_api_1['6'][i])
    self.assertTrue(test_utils.call_until_true(srv1_v6_addr_assigned,
                    CONF.validation.ping_timeout, 1))
So this is to add support of args and kwargs in call_until_true,
and to log the cost time when call_until_true returns True or
False for debugging.
