Public bug reported:
Per bp/improve-dvr-l3-agent-binding, command "neutron
l3-agent-list-hosting-router ROUTER" couldn't show bindings for DVR routers on
agents in 'dvr' mode now.
It's good to hide the implicit *binding* between DVR router and agent in 'dvr'
mode, for DVR routers should come and go as dvr serviced port on host come and
go, not for manually managed.
But it still be possible to run "neutron l3-agent-router-remove AGENT ROUTER"
to remove a DVR router from an agent in 'dvr' mode. This will make DVR router
namespace deleted, and l3 networking on that node crashed.
We should add a checking for removing router from agent in 'dvr' mode, and
forbidden processing going on.
