Floating IPs cannot be associated in a HA router setup

[Paulo Matias]

Regression introduced by https://github.com/openstack/neutron-lib/commit/0440878cc61737cf68a2f5780fc8af57845078fd

When Neutron is deployed to implement a HA router setup, Horizon is not capable to list targets for floating IP association. The user receives only a "No Ports Available" message and is thus unable to associate any floating IP through Horizon.

This happens because get_reachable_subnets [1] always returns an empty set, issue which is caused by the absence of the new device owner flag for HA router interface ("network:ha_router_replicated_interface") in ROUTER_INTERFACE_OWNERS [2].

I will send a patch to gerrit in a few minutes.

Expected result: The user should be able to associate a floating IP to an instance using Horizon.

Actual result: The user cannot associate any floating IP because "Port to be associated" only displays "No Ports Available".

Steps to reproduce:
* Deploy the environment
* Create an external network, a project network, and a router between them
* Launch an instance
* Allocate a floating IP
* Try to associate a floating IP to the instance

Environment:
* OpenStack-Ansible, master branch
* Multi-node setup
* Default neutron setup (ml2.lxb)

    Add the new device owner flag for HA router interface

    Changeset I89b247bdac3aee1e47ee8a1c9f1cb2c385019a51 introduced a new
    device owner flag for HA router interfaces which was still not included
    in Horizon's ROUTER_INTERFACE_OWNERS.
