Stephen Finucane c0aef97c49 netutils: Ignore 'use_ipv6' for network templates
Nova supports file injection of network templates. Putting these in a
config drive is the only way to configure networking without DHCP.

At present, setting the 'use_ipv6' config option to False prevents the
generation of IPv6 network info, even if there are IPv6 networks
available. This was fine when using nova-network, where the same config
option is used to control generation of these subnets. However, a
mismatch between this nova option and equivalent IPv6 options in neutron
would result in IPv6 packets being dropped.

Seeing as there is apparent reason for not including IPv6 network info
when IPv6 capable networks are present, we can ignore this option.
Instead, we include info for all available networks in the template, be
they IPv4 or IPv6.

To learn how to use Nova's API, consult the documentation
available online at:

    http://developer.openstack.org/api-guide/compute/
    http://developer.openstack.org/api-ref/compute/

For more information on OpenStack APIs, SDKs and CLIs,
please see:

Operators
---------

To learn how to deploy and configure OpenStack Nova, consult the
documentation available online at:

    http://docs.openstack.org

For information about the different compute (hypervisor) drivers
supported by Nova, please read:

   http://docs.openstack.org/developer/nova/feature_classification.html

In the unfortunate event that bugs are discovered, they should
be reported to the appropriate bug tracker. If you obtained
the software from a 3rd party operating system vendor, it is
often wise to use their own bug tracker for reporting problems.
In all other cases use the master OpenStack bug tracker,
available at:

   http://bugs.launchpad.net/nova
