Increase address allocation size for subnet pool tests with IPv4
This patch is increasing the address allocation size for the subnet pool
tests with IPv4 (SubnetPoolsTest class) by:
* Changing the subnet_cidr from /31 to /29
* Changing the max_prefixlen from 31 to 30
The reason for that is because some ML2 drivers such as OVN would create
a new port in Neutron at the moment that a network is created for being
used by the metadata agent. This new port will allocate an IP from the
subnet which was causing the tests below to fail with a "No more IP
addresses available on network ..." error:
SubnetPoolsTest.test_create_subnet_from_pool_with_prefixlen
SubnetPoolsTest.test_create_subnet_from_pool_with_quota
SubnetPoolsTest.test_create_subnet_from_pool_with_subnet_cidr
