Tempest Rhel7: subnet configures with 0.0.0.0 when sending gateway None

[Nagendra Prasath]

Build: Rhel7 2.20-65~juno

Tempest Case: tempest.api.network.test_networks.NetworksIpV6TestJSON.test_create_list_subnet_with_no_gw64_one_network

As a part of this case, when subnet is created with gateway=None, it gets configured with gateway == 0.0.0.0 which is unacceptable.

Posted Body:
        Body: {"subnet": {"ip_version": 4, "network_id": "cfc8734b-9854-4545-8dea-a52ac2510897", "cidr": "10.100.0.0/28", "gateway_ip": null}}
