[OVN] OVN driver to adapt to enable_distributed_floating_ip changes
Prior to this patch, if the [ovn]/enable_distributed_floating_ip
configuration option changed in an existing environment the OVN
driver wouldn't adapt to it requiring administrators to clear up the
"external_mac" column from the NAT table manually for the existing
floating ips.
With this patch, OVN will automatically correct existing NAT entries for
floating ips whenever this option changes.
To make the code simpler when handling the port up/down event this patch
always set the logical_port and the neutron:fip_external_mac key in the
external_ids column of the NAT entry when creating the floating ip.
Note that we are not using the maintenance task for this either, we are
re-using the event that set/unset the "external_mac" column for this
because, whenenver the service is restarted (after the configuration is
changed, we need to restart for it to take effect) the IDL will re-trigger
those events.

Title:
[OVN] enable_distributed_floating_ip changes are not applied for
existing NAT entries
Status in neutron:
Fix Released
Bug description:
In OVN, if we change the value of the
[ovn]/enable_distributed_floating_ip configuration option and restart
the service, the OVN driver will not reflect this change in the
existing NAT entries.
Say you have a enable_distributed_floating_ip as True and then you
change it to False, new NAT entries (floating ips) will have the
"external_mac" column empty when they are created but, pre-existing
NAT entries won't be updated and will have their "external_mac" set.
Requiring someone to manually update the OVN database to clear out
that field.
