Use Tauri as a desktop application framework

[sniok]

We currently use Electron as a framework for the desktop Headlamp application. It has several some downsides such as big installation size and slow startup.

We could instead use Tauri as a replacement for Electron. Since it had 2.0 stable release I think this is a good time to consider migration. So far it seems that it has every feature we would need:

Running backend as a sidecar
https://tauri.app/develop/sidecar/

Communicating with the frontend
https://tauri.app/concept/inter-process-communication/

Security and permissions
https://tauri.app/security/

Customizing menu
https://tauri.app/learn/system-tray/

Running shell commands
https://tauri.app/plugin/shell/

One great thing about Tauri is that you could run code on the frontend that would usually be run on the electron side, for example you could add a menu item right from the frontend.

This means we could migrate our current electron logic to frontend without having to deal with Rust.

Pros:

• Faster startup time
• Small executable
• Desktop app logic in the frontend codebase

Cons:

• Parts of code that need to be written in Rust which may be not familiar

This migration would take a lot work:

• Migrate Menu customization from plugins
• Migrate plugin management
• Need to rewrite our current electron logic
• Need to setup CI for building/bundling from scratch
• Figure out signing
