Public bug reported:

This bug is related to [1] and the mentioned bugs and patches in the
commit message.

Context:
* ML2/OVN driver.
* Distributed floating IPs.

When a router has "mixed type networks" (tunnelled and not tunnelled
networks), the VLAN/flat LRP should have the flag 'reside-on-redirect-
chassis' to True. If the router has only VLAN/flat networks, the flag
'reside-on-redirect-chassis' should be False and 'redirect-
type'='bridge'.

The patch [1] does not consider the router LRP addition/deletion. For
example, if we initially add the VLAN/flat network to the router, the
router won't have "mixed type networks". If we then add a tunnelled
network, we don't update the VLAN/flat LRP. The same scenario happens
when we remove a tunnelled LRP and the router has only VLAN/flat
networks.
