When using networks without DHCP enabled and "flat_injected" set to True,
the interfaces template is injected in the associated instances or
included in the config drive metadata.
The template includes the interface name, based on a progressive numbering
(eth0, eth1, etc). In case of multiple nics, there's no clear way to
identify the interfaces in the guest OS if the actual interface naming
differs, this is especially valid for Windows instances.
Since the MAC address (hardware address) assigned to each vNIC identifies
uniquely the interface, providing the mac address during the template
generation solves the issue.

Update interfaces.template to support ipv6 based dns servers. Make
sure we validate the version of the ip addresses before we
fill them in.

Libvirt's LXC implementation exposes a read-only `/proc/sys/net` to the
guests. This causes some of the guest's default network configuration scripts
to fail.
This patch works-around the issue by using `post-up` hooks to configure IPv6.

If you have more than one interface and IPv6 enabled, then the interfaces file
emitted would have the incorrect syntax: the `auto eth1` line would be
appended to the end of the `gateway` line of the previous stanza.
This was a result of improper whitespace control in the Jinja template which
this patch fixes.
In order to prevent regressions, this patch swaps out the existing tests with
corresponding tests that are whitespace sensitive. This is important because
it's difficult to tweak Jinja templates in a way that fixes the whitespace
for one scenario while not breaking another.

Cheetah is unmaintained since 2010 and it's unlikely to get Python3
support soon. Also, the rest of OpenStack (mostly) standardized on
Jinja2.

Launching an instance when using network injection on a network
containing a subnet that has no gateway fails in scheduling with
a KeyError when using a legacy network_info provider and generates
an invalid network file for the others.
The following changes were done:
* The legacy transformer for network_info now always provides
a gateway/gateway_v6 field, with a value of None if no gateway
is available (this is similar to the other fields that are empty).
* The interfaces template was modified to include the gateway line
only if a gateway is provided for the interface.
