This pull request modifies the IC-OS configuration types library (rs/ic_os/config_types/src/lib.rs).

Please ensure you have followed the Configuration Update Protocol guidelines——particularly if adding a new enum or enum variants:

Enum Variant Forward Compatibility Guidelines: If adding a new enum or new variants to an enum, ensure older versions can handle unknown variants gracefully by using #[serde(other)] on a fallback variant. See examples: GuestVMType::Unknown and Ipv6Config::Unknown.

For complete guidelines, see the documentation at the top of rs/ic_os/config_types/src/lib.rs.

I want to follow up on this with another reorganization, but this is enough for now!

Strictly a refactor
