    Fix remove_router_from_l3_agent for 'dvr' mode agent
    
    It's possible to run command remove_router_from_l3_agent to remove
    a DVR router from an agent in 'dvr' mode. But the implicit *binding*
    between DVR router and agent in 'dvr' mode should come and go as
    dvr serviced port on host come and go, not manually managed.

Title:
  DVR router should not allow manually removed from an agent in 'dvr'
  mode

Status in neutron:
  Fix Released

Bug description:
  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.
