Introduce aws-sdk-rust as rusoto S3 replacement (#2802)

- `aws-smithy-http`: Needed because of `SdkBody` see
smithy-lang/smithy-rs#1759
- `aws-types`: Needed because of `SharedCredentialsProvider`, the
recommended way from aws is something like
`aws_config::from_env().region("us-east-1").load().await` but that is
problematic because of:

- `sync -> async ` in the creation of S3Client and i don't want to
change the signature of any method in this class.
- We do not need the four default steps in
https://github.com/awslabs/aws-sdk-rust/blob/main/sdk/aws-config/src/default_provider/credentials.rs#L235

- `Hyper`: Similar to what's currently doing Rusoto in
https://github.com/rusoto/rusoto/blob/master/rusoto/signature/src/signature.rs#L59
to stream the body, see also
awslabs/aws-sdk-rust#361
