Title:
  network with VLAN ID not in network_vlan_ranges shouldn't be created
  successfully for ml2

Status in OpenStack Neutron (virtual network service):
  Invalid

Bug description:
  I have network_vlan_ranges = physnet1:1000:2999 in ml2_conf.ini. I can create a net with  '--provider:segmentation_id 4000' which is out of the range 1000:2999.
  I found a debug log in the method reserve_provider_segment in type_vlan.py, but I think this is not enough because this makes the VLAN range in network_vlan_ranges no sense.

  In reserve_provider_segment type_vlan.py,

              except sa.orm.exc.NoResultFound:
                  LOG.debug(_("Reserving specific vlan %(vlan_id)s on physical "
                              "network %(physical_network)s outside pool"),
                            {'vlan_id': vlan_id,
                             'physical_network': physical_network})
                  alloc = VlanAllocation(physical_network=physical_network,
                                         vlan_id=vlan_id,
                                         allocated=True)
                  session.add(alloc)
