    add 4094 to fix the range of available local vlans

    in fact the range of available local vlan is 1-4094,
    but when initialization of the local vlan in ovs_neutron_agent,
    self.available_local_vlans is set([1,2,3...4093]),omit 4094
    This causes a problem that ovs-agent will not use 4094 as local vlan

    modify moves.range(p_const.MIN_VLAN_TAG, p_const.MAX_VLAN_TAG+1)
