If we have two computes, and each is network node, that means both hosts 
a router.

Let say we have two tenants with two instance and two compute hosts.


But neutron have no idea about this. Someone asks him 'put router to any 
l3-agent'. And it put router1 on compute2, and router2 on compute1.

It will works. Until not. If compute1 goes down it not only affects 
instance1, but also will cause disruption for network services for tenant2.

And there is no way to control l3 agent placement, no respect to 
availability zones, instance placement, aggregates, etc.
