Support durable functions

[lym953]

This issue is for discussions about Lambda Durable Functions.

Context

AWS Lambda released Durable Functions:

• Announcement: Build multi-step applications and AI workflows with AWS Lambda durable functions
• Product page: AWS Lambda durable functions
• Doc: Lambda durable functions
• Blog: Best practices for Lambda durable functions using a fraud detection example

And we are going to support it in Datadog as well.

Discussion topics

Feel free to leave a comment if you have any idea on its Datadog integration, e.g.

• what observability features you want to have in Datadog
• when you want it to be ready by
• anything special with your use case / architecture that you want us to take into account when designing the solution
• or just show your interest!

It's out! Please follow this doc (https://docs.datadoghq.com/serverless/aws_lambda/durable_functions/) to instrument your function, and feel free to explore:

1. the new Executions tab in the Lambda view's side panel
2. flame graph in trace view, for the durable execution's trace
3. "Durable Function Executions" section in trace view's Infrastructure tab

More docs are coming soon.
A few UI fixes are still on the way, and will probably be out within a week.
