Motivation and Context
Fixes awslabs/aws-sdk-rust#973
Description
Prior to the PR, if a customer explicitly passed a credentials provider to a client's config
Builder::set_credentials_provider, what's passed did not override a credentials provider previously set (actual use case).While in general, we recommend customers single-source a credentials provider through aws_config::ConfigLoader::credentials_provider, we should eliminate the said footgun in case they directly pass a credentials provider to a client's config
Builder.The PR reverts test signature updates in #3156 (in hindsight, having to update test signatures in that PR was a sign of regression).
Testing
Added a Kotlin test to
