Title:
  l3-agent restart fails to remove qrouter namespace

Status in neutron:
  Expired

Bug description:
  When a router is removed while a l3-agent is stopped, then started
  again the qrouter namespace will fail to be destroyed because the
  driver returns a 'Device or resource busy' error.   The reason for the
  error is the metadata proxy is still running on the namespace.

  The metadata proxy code has recently been refactored and no longer is
  called in the _destroy_router_namespace() method.  In the use case of
  this bug, there is no ri/router object since it has been removed, only
  the namespace remains.  The new before_router_removed() method
  requires a router object.

  Changes will be required in both the l3-agent code and metadata proxy
  service code to resolve this bug.
