[Core feature] Flytekit Rust SDK

[pingsutw]

Motivation: Why do you think this is important?

Rust code can be run inside the container, and users don't need to install the Python SDK

Goal: What should the final outcome look like, ideally?

An SDK, similar to Python, but written in Rust. This SDK should have

• Add a Entrypoint to load the rust code
• Add a Rust file system to download input/output/user code
• Add Rust Type Transformers
• Add a Rust task decorator

@pingsutw i and hunk we should write a small doc with a diagram of all
Components we want in rust.

Type transformer is probably not needed.
We should add checkpoints
