Regression in unhardcoding private/floating predefined ranges

[Matthew Mosesohn]

https://bugs.launchpad.net/fuel/+bug/1349702 is a very long bug in progress with https://review.openstack.org/#/c/228514/ already merged, but https://review.openstack.org/#/c/228514/ reverts the functionality merged in it. We should revert or fix fuel-library master so that the following functionality is read and parsed from astute.yaml:
$quantum_settings['default_private_net'] = 'net04'
$quantum_settings['default_floating_net'] = 'net04_ext'
$quantum_settings['default_router'] = 'router04'

Predefined networks hash will work as before.
