rCOMM7c253be3d099: [services] Tunnelbroker - Creating `main.rs` entry point file for Rust

Summary

This diff is a part of the flat diffs stack to transform the current Tunnelbroker project into a Rust app by calling the current C++ codebase from Rust. The related transition task is ENG-1072.

This diff creates a Rust application entry point file main.rs and calls the initialization function (D5429) from the current C++ codebase.

Related Linear task: ENG-2092

CI Notice:
The CI will fail on this and further diffs until the D5461 where the changes to CI build commands are made.
This stack will be landed all in one to prevent CI from failing on diffs out of this stack.

Test Plan

1. CI Testing:
These diff changes are included as a part of the stack in the later D5461 diff, where the changes to CI build commands are made. The CI succeded on the D5461 which reflects that this changes are passing the build.

2. Manually testing:
These diff changes can be tested in the middle of the stack at D5436. To test it patch to D5436 using arc patch D5436, run nix develop. Go to tunnelbroker service directory services/tunnelbroker and run the Cargo building process cargo build or cargo run.
The Rust application will be successfully built.

4	I guess this is highly unrecommended: https://doc.rust-lang.org/std/macro.include.html Leads to potential footguns around what is "defined" through it We should include the C++ codebase exposed functions to the Rust app. In a regular Rust app we shouldn't do this, but in our scenario, seems that this is the only way to include headers according to the cxx documentation.

don't feel like blocking this work, since we have the goal of transitioning away from C++ eventually. So the issue of include! hygiene might not be relevant in the future.
