Maintenance: Add E2E tests for Idempotency utility to verify behaviour with durable functions

[ConnorKirk]

Summary

The E2E tests should:

• Create a durable function
• Verify that a durable execution containing a wait step executes successfully
• Verify that a duplicate durable execution with the same payload as an earlier one returns the same result
• Verify that a durable execution raises the IdempotencyAlreadyInProgress error if there is an existing execution with the same payload.

Why is this needed?

Verify the behaviour of the idempotency utility with durable functions and catch regressions

Which area does this relate to?

Idempotency

Happy to work on this one

Hi @jaimellamasi - that's great!

Before you start with the implementation, I'd suggest that you share a high level plan so we can agree on the testing strategy. We tend to be fairly opinionated in the way these tests are carried out, so it'd be great to agree in advance and avoid rework on your side.
