* [#367] Enhanced multi-lang `AWSCredentialsProvider=...` decoder and construction. + added support for external ids (issue #367) + added support for endpoint+region (e.g., STS via VPC) * Multiple multi-lang edits to introduce logging and additional tests. + added `ENDPOINT_REGION` nested key for a simpler Cx experience + deduplicated, and improved, logic w.r.t. CredentialsProvider construction to NOT swallow Exceptions * Relocated `multilang.properties` from `main/resources` to `test/resources`
