A reimplementation of aw-server in Rust

Primary features missing:

• Safe CORS (not allow all, fix dynamic CORS in rocket_cors upstream)

Caveats:

• Some refactoring is needed
• Lots of TODO and FIXME comments

Bugs:

• Memory leak during Bucket import? (wtf rust?)

Features missing compared to aw-server python:

• Swagger support

cargo build --release

Install rust nightly and run

cargo run
