Updating mac_address of port doesn't update its autoconfigured IPv6 address

[Derek Higgins]

PUT /v2.0/ports/d38564ff-8a98-4a21-a162-9b2841c78ebc.json HTTP/1.1
...
{"port": {"mac_address": "fa:16:3e:d2:03:61"}}

This updates the ports MAC address but doesn't update the IP address.
If using slaac or stateless address mode it should as the IP address is derived for the MAC address.

    Update auto-addresses on MAC change

    On MAC update add an entry for auto-addressed IPs so
    that they get removed and re-allocated.

    Also Fix the unit test that was testing for this, so that
    it checks the IP for the new updated port (it was checking
    the port before the update).

[Derek Higgins (derekh)]

The previous version of this patch was reverted due to a regression that occurred when a port had both ipv6 and ipv4 ip addresses, see

    Update auto-addresses on MAC change

    On MAC update add an entry for auto-addressed IPs so
    that they get removed and re-allocated.

    Also add a check to ensure the length of fixed_ips in the result
    is what was expected i.e. ensure we replaced the IP's(as is the current
    behaviour) and not just added to the list.
