Fix setting correct 'reside-on-chassis-redirect' in the maintenance task
Setting of the 'reside-on-chassis-redirect' was skipped for LRP ports of
the provider tenant networks in patch [1] but later patch [2] removed
this limitation from the ovn_client but not from the maintenance task.
Due to that this option wasn't updated after e.g. change of the
'enable_distributed_floating_ip' config option and connectivity to the
existing Floating IPs associated to the ports in vlan tenant networks
was broken.
This patch removes that limitation and this option is now updated for
all of the Logical_Router_Ports for vlan networks, not only for external
gateways.

Title:
Switch from distributed to centralized Floating IPs breaks
connectivity to the existing FIPs
Status in neutron:
Fix Released
Bug description:
This affects only ML2/OVN deployments. I was checking it with
initially enabled distributed floating ips
(enable_distributed_floating_ip=True in the neutron ml2 plugin's
config file).
Steps to reproduce the issue:
1. Create vlan tenant network -- THIS IS VERY IMPORTANT, USING TUNNEL
NETWORKS WILL NOT CAUSE THAT PROBLEM AT ALL
2. Create external network - can be vlan or flat
3. Create router and attach vlan tenant network to that router
4. Set external network as router's gateway
5. Create vm connected to that vlan tenant network and add Floating IP to it,
6. Check connectivity to the VM using Floating IP - all works fine until
now...
7. Change 'enable_distributed_floating_ip' config option in Neutron to be
FALSE
8. Restart neutron-server
9. FIP is not working anymore - it is because SNAT_AND_DNAT entry was changed
to be centralized (no external_mac not set anymore in ovn-nb) but
Logical_Router_Port still have option "reside-on-redirect-chassis" set to
"false". After updating it manually to "True" connectiity over centralized
gateway chassis works again.
This option reside-on-redirect-chassis was added with patch
https://review.opendev.org/c/openstack/neutron/+/871252. Additionally
patch https://review.opendev.org/c/openstack/neutron/+/878450 added
maintenance task to set correct value of the redirect-type in the
Logical_Router's gateway port. But it seems that we are missing update
of the 'reside-on-redirect-chassis' option for the existing
Logical_Router_Ports when this config option is changed. Maybe we
should have maintenance task for that also.
