Fixed IPs of dhcp_port are not updated when a new subnet is added to the network.

Start fresh (i.e., no routers/networks/subnets/ports).<br/> 2. Create a neutron tenant network (say t1)<br/> 3. Create an IPv4 subnet (say s1 with CIDR 10.0.0.0/24) on the network t1.<br/> 4. Create an IPv6 SLAAC subnet (say s2 with 2001:db8::/64) on the network t1.</p> <p>After step 3 above when we query port info from mdsal, we can see a port with device_owner: "network:dhcp" and fixed_ip </p> {ip_address: "10.0.0.2"} <p>Step 4 does not trigger any port update event from Neutron eventhough Neutron db updates the fixed_ips of the dhcp port with an IPv6 address from S2 CIDR. <br/> Patch <a href="https://review.openstack.org/#/c/271223/" class="external-link" target="_blank" rel="nofollow noopener">https://review.openstack.org/#/c/271223/</a> triggers a port_update event in Neutron for IPv6 auto-address subnets.</p> <p>OpenStack Neutron patch <a href="https://review.openstack.org/#/c/271223/" class="external-link" target="_blank" rel="nofollow noopener">https://review.openstack.org/#/c/271223/</a> is merged in Master branch.
