OpenStack Networking (Neutron)

This patch adds an extra checking to ensure the "reside-on-redirect-chassis" is set to true for the logical router port associated to vlan provider network despite having the "ovn_distributed_floating_ip" enabled or not. This is needed as there is an OVN bug [1] making it not work as expected. Note setting this to true has implications as the traffic will be centrallized (but not tunneled) through the node with the gateway port. The expected behavior of this flag, once [1] is fixed is: - reside-on-redirect-chassis flag to False: means traffic goes tunneled to the controller with the gateway port. Means it requires extra MTU reduction to work. - reside-on-redirect-chassis flag to True: means traffic is not tunneled to the controller with the gateway port, but the traffic is centralized through the controller with the gateway port. Thus it does not require extra MTU reduction. - reside-on-redirect-chassis to False, but with ovn-chassis-mac-mappings configured: means the traffic is fully distributed and it is not being tunneled, nor sent, through the controller with the gateway port. This is the preferred option as it does not require MTU reduction and it avoids the extra hop. However it is not working as expected, therefore the fallback to set reside-on-redirect-chassis to True.
