Document the keep parameter of archive.extracted state
If interface type is slave, not auto set hwaddr

If auto set hwaddr for bond, it will use the true hwaddr for the first time. It's correct.
But interfaces will display same hwaddr in a bond by use 'ifconfig' or 'ip link show' when bond running,
Then they will reset to same hwaddr when execute state again, os will prompt like:

    Bringing up interface bond0:  Device eth2 has different MAC address than expected, ignoring.
                                                           [  OK  ]

eth2 interface in this example will eliminate from bond0. It's incorrect.
