Bug

What happened:

error[E0252]: the name `tls` is defined multiple times
  --> /home/iajoiner/.cargo/registry/src/github.com-1ecc6299db9ec823/rusoto_core-0.48.0/src/lib.rs:25:5
   |
23 | use hyper_rustls as tls;
   |     ------------------- previous import of the module `tls` here
24 | #[cfg(feature = "native-tls")]
25 | use hyper_tls as tls;
   |     ^^^^^^^^^^^^^^^^ `tls` reimported here
   |
   = note: `tls` must be defined only once in the type namespace of this module
help: you can use `as` to change the binding name of the import

What you expected to happen:

How to reproduce it:
Run cargo test at the top level

More details:
The essence of the problem is that we are using an unofficial AWS SDK crate, rusoto, that has been in maintenance mode since 2020 when there is in fact an official AWS SDK crate, https://github.com/awslabs/aws-sdk-rust now. Since rusoto has two mutually exclusive features without adding a compiler error to detect them being used in combination we have this bug.

OK this is a duplicate of #677. We need to fix this and add the top level CI so that any future regression will be detected.
