    dhcp: handle advertise_mtu=True when plugin does not set mtu values
    
    DHCP agent may be used by plugins that don't set mtu value for networks.
    Handle the case by not passing the DHCP option when network does not
    have the value set.
    
    Most plugins do set the value though, since it's enforced in base db
    plugin class.

Title:
  advertise_mtu=True for DHCP agent when plugin does not pass .mtu
  attribute for networks results in agent failure

Status in neutron:
  Fix Released

Bug description:
  In that case, you would see a traceback with the following lines:

        File "neutron/agent/linux/dhcp.py", line 371, in _build_cmdline_callback
          mtu = self.network.mtu
      AttributeError: 'FakeV4Network' object has no attribute 'mtu'

  We should check whether plugin passed mtu attribute before accessing
  it.
