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.

We had an history mapping for InternalApi to InternalNetwork. If we
remove it then heat will want to destroy InternalNetwork and create
InternalApi which cannot work during upgrade.
This adds compat name parameters to network_data.yaml.

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.

Makes it possible to resolve network subnets within a service
template; the data is transported into a new property ServiceData
wired into every service which hopefully is generic enough to
be extended in the future and transport more data.
Data can be consumed in service templates to set config values
which need to know what is the subnet where a deamon operates (for
example the Ceph Public vs Cluster network).

This moves the hard-coded networks from the default environment,
and provides the first step towards enabling composable networks.
