add test for create subnet with default gateway and conflict allocation pool

Create subnet with default gateway and conflict allocation pool should return
status code 409:
$ quantum subnet-create net1 --allocation-pool start=10.0.0.1,end=10.0.0.5 \
10.0.0.0/24
Found overlapping allocation pools:{u'start': u'10.0.0.1',
u'end': u'10.0.0.5'} 10.0.0.1 for subnet 10.0.0.0/24.
