[PATCH proxmox v3 10/38] 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`

Signed-off-by: Christoph Heiss <c.heiss@proxmox.com>
---
Changes v2 -> v3:
  * changed `ProxmoxProduct` variants to PascalCase
  * fixed typo in `Display` impl

Changes v1 -> v2:
  * no changes

Note: The custom `BootType` enum was retained, as using an existing
variant proved to be much more work/hacky due to different
(de-)serialization expectations.
