When writing metadata, copy any released metadata to the legacy index file

Fixes: https://bugs.launchpad.net/juju-core/+bug/1396981

The legacy index.json file needs to be written out to contain any released metadata. This allows the current release scripts to work.

Fixed lp:1395908 - disabled NICs from lshw stay disabled

With this fix the MAAS provider takes the disabled="true"
attribute of <network/> elements into account when deciding
which should be the primary network interface on the machine.
The end result is juju-br0 will be configured to use the first
enabled network interface.

Live tested on MAAS.
