Change Details

Copy some code from other rust services that access DynamoDB. I'm going to prioritize https://linear.app/comm/issue/ENG-2311/shared-rust-code-across-services as soon as I'm done with the main goal. I'm postponing it for now as creating a shared Rust lib and figuring out the common interface might take some time. In this diff I'm not changing anything significant - the changes are about removing the code that isn't relevant for this service and would cause warnings. Depends on D6853

Create a new lib where all the common database code for Rust services can be placed. Depends on D6853
