Fix rustfmt formatting errors in kafka module and aws module

Applied nightly rustfmt formatting fixes to pass `cargo +nightly fmt --check`:
- hydro_test/src/kafka/mod.rs: reorder imports, reformat long lines
  (consumer creation, flat_map closure, Err match arm, function signatures,
  function call arguments)
- hydro_deploy/core/src/aws.rs: expand struct literal to multi-line format
