T1762: Deploy NetBox

Summary

This change is a proof of concept we can use NetBox
to generate information for node pillar

Usage: utils/netbox/pillarize.py <node name>

Additional credits:
cidr_to_netmask method by Trenton McKinney

We also need pillar/core/network Drake content

Support for IPv6 and for dedicated baremetal instances. Rebased.

Blocked by T1859 change.

Rebased. Use default_gateways and default_gateways_virt fields. Add support for IPv6.

What's missing compared to https://devcentral.nasqueron.org/source/operations/browse/main/pillar/nodes/nodes.sls?

IPv6 flags at network level
- ipv6_native`
- ipv6_tunnel
Flags at interface level
- ipv4_ovh_failover: could be derived from a new specific tag "IPFO" applied to failover IPs, and the already existing tag "OVH"
- skip_interface_configuration: used only on Eglide, currently out of scope of NetBox, but if we use this, we'll need to add Eglide too -> custom field with the same name

We then need to carefully compare roles and information, and that's ready to switch from nodes["router-001"] to node directly.

To check if GRE configuration don't try to read IPs from the nodes. If so, we can output a specific pillar entry specific for GRE tunnels, especially as we've all the needed information in the GRE interfaces.

We don't need any flag ipv6_ovh_fix, as we used instead a module method: network_utils.can_directly_be_discovered

Next: ipv6_dhcp_duid flag at interface level

Also gateways are now a multi-value field to allow IPv4 + IPv6

OK, but for hervil, we need to figure how to output 255.255.255.255 as netmask

I removed the priority and name entries from the generated pillar, as they are not used by Salt in our current setup.
Keeping only the fields actually consumed by the states makes the pillar cleaner and avoids maintaining redundant data.

Remove an incorrect character from the code (star that shouldn't be there).

We need to use OrderedDict from the collections module because the pillar generation script must preserve the order of the information. This ensures that the generated pillar file remains consistent and human-readable. Maintaining a stable order also makes it easier to review changes, compare versions, and debug configurations.

This revision now requires changes to proceed.Wed, Feb 25, 14:02
