Comment 3 for bug 1843557

@dmitriis this problem is not specific to the lp-management network, rather it is a result of having a single schedule space for routers which will now have a mix of l3agent with some having access to the external network (e.g. those running on nova-compute hosts) and some not (those running on octavia hosts). We could possibly explore the idea of having a dummy neutron az for octavia units but i think thats going to cause complications for required l2 scheduling so removing the l3-agent from octavia units is probably the way to go. I am testing it now so we'll see.
