This change renders the IPv6 versions of the isolated
networks using j2. To allow for backward compatibility,
there will be 2 versions of the network definitions,
<network>.yaml and <network>_v6.yaml. If the ip_subnet
contains an IPv6 address, or if ipv6: true is set on the
network definition in network_data.yaml, then the
<network>.yaml version will contain an IPv6 definition,
otherwise the <network>.yaml will be IPv4, and the
<network>_v6.yaml will be IPv6.
In a future follow-up patch, we will probably only
create the required versions of the networks, either
IPv4, IPv6, not both.
The ipv6_subnet, ipv6_allocation_pools, and ipv6_gateway
settings in the network_data.yaml definition file are
used for the <network>_v6.yaml network definition.
Note that these subnet/cidr/gateway definitions only set
the defaults, which can be overridden with parameters
set in an environment file.
Since the parameters for IP and subnet range are the
same (e.g. InternalApiNetCidr applies to both IPv4/v6),
only one version can be used at a time. If an operator
wishes to use dual-stack IPv4/IPv6, then two different
networks should be created, and both networks can be
applied to a single interface.
Note that the workflow for the operator is the same as
before this change, but a new example template has been
added to environments/network-environment-v6.yaml.

Use the network.network.j2.yaml to render these files, instead
of relying on the hard-coded versions.
Note this doesn't currently consider the _v6 templates as we may want
to deprecate these and instead rely on an ipv6 specific network_data file,
or perhaps make the network/network.network.j2.yaml generic and able to
detect the version from the cidr?

We were missing the square brackets around the list of arguments
for get_attr when building the networks cidr output.
This passed CI because Heat does not fail validation and Ceph (which
is consuming the cidr output) is tested with a single network (ctlplane)
which does not build the output using the same templates.

This change adds templates that are used to create network and
port definition templates for each network that is defined in
network_data.yaml. In order to render the templates, additional
fields have been added to the network_data.yaml file. If this
optional data is present, it will be used to populate the default
parameter values in the network template.
The only required parameters in the network_data.yaml file is
the network name. If the network will have IPv6 addresses, then
ipv6: true must be set on the network.
The existing networks have been modeled in the network_data.yaml,
but until these templates are removed from the j2_excludes.yaml
file they will not be generated on the fly. Any additional
networks will have templates generated.
This change also removes an unnecessary conditional from the
networks.j2.yaml file, since InternalApiNetwork doesn't need
to be reformatted as InternalNetwork (it's only used in this
one file).
A follow-up patch will remove the existing network definitions
so all networks are created dynamically.
