[pve-devel] [PATCH installer 10/14] post-hook: add network interface name and pinning status

[Christoph Heiss]

Adds a new `name` and `is-pinned` attribute to each reported network interface in
the post-hook data.

Also increments the minor schema version by one, as it is a
backwards-compatible change.
