[Tagging] Fwd: Walking & Cycling Node Network tagging: undoing the hijacking of rcn and rwn

I think it's the best AND the easiest solution.
Network configuration type is currently not tagged. Nederland, Belgium and
Germany decided to use rcn exclusively for the cycle node networks. Later
they copied that to rwn for the emerging walking node networks.
We now want to correct that, but we also want a clear difference between
the network condfigurations. Then renderers and other data users can make
the distinction.

We have considered using another network=* value. But the transport mode is
still in there, as is the geographical scope. So you would need extra
values for all combinations of mode, scope and config. If yet another
network config type emerges, you will need more network values. Every data
user has to decode the values to know what's going on. While what we want
is just to indicate that this particular rcn route is part of a node

This is true for all transport modes (now and future) and for all
geographical scopes, now and future.

So we came to the solution that it is by far the most effective and at the
same time the easiest solution to just add the information that a route is
part of a node network in a separate tag. The bonus is that other network
systems can be accommodated as well. E.g. some regions and some nature
parks in Nederland have a "colour choice network", where you can follow a
(self-planned) sequence of signposted coloured routes.

The extra bonus of this solution is that currently tagged node network
routes need no retagging, just addition of the information that they are
part of a node network. This allows renderers and other data users to
refine the display or handling of the existing rXn routes.

We thought of network_type as a key. This is not a new key, it has some
non-conflicting usage. We could introduce a new key as a namespaced
variant: network:type=*.

If this is still confusing: feel free to suggest better names and values to
indicate that a route belongs to a network system of the node variety.
