Description of your changes

As described in the linked issue, this PR reduces the reliance on the soon-to-be-put-in-maintenance-mode aws-sdk (v2). The PR swaps its usage for the more modular AWS SDK v3 for JavaScript wherever possible.

The repo still has aws-sdk as dev dependency, however this has now been moved from the root level and placed in the packages/tracer package since it's now the only utility that requires this version of the SDK to support the tracer.captureAWS and tracer.captureAWSClient methods. The SDK is only used as dev dependency to provide IDE support for the integration test functions.

To validate the changes, see the unit tests below this PR as well as the successful result of this e2e test run.

Once merged this PR will close #1404.
