[pdm-devel] [PATCH proxmox 05/13] installer-types: add common types used by the installer

[Christoph Heiss <c.heiss@proxmox.com>]

These moves common type definitions used throughout in the installer in
it's own crate, so they can be re-used in other places.

Some types are also renamed to improve clarity:

- `NetdevWithMac` -> `NetworkInterface`
- `SysInfo` -> `SystemInfo`
