[SVLS-4148] Inject trace context into AWS Stepfunction executions

[agocs]

What does this PR do?

Adds a plugin for AWS Stepfunctions that injects the datadog trace context into the input parameter of a startExecution or startSyncExecution request, if the input parameter is already a JSON object.

Screenshot of a datadog trace showing a JS lambda function invoking a Step Function.

Motivation

SVLS-4148

Serverless Integrations has added the ability to trace Stepfunction executions, and we want to be able to link Stepfunction executions with upstream traces. We do so by inspecting input._datadog in the Logs to Traces Reducer.

Plugin Checklist

• Unit tests.

It seems localstack supports the step function API - can we have a few E2E tests that check the generated spans' shape?
