Description of your changes

In #1661 we have made changes to the integration test and as a result we inadvertently introduced some flakiness. This PR addresses this by applying the following fixes:

• reviewed & made unique all the test suffix across utilities
• introduce runtime key in SSM secret string name/path
• revisited X-Ray trace retrieval and moved to using function name instead of ARN
• unified workflow to use single job
