aws-stepfunctions-tasks: Support for new HTTPS Endpoint integration

[MathieuGilbert]

Describe the feature

Support for the newly released HTTPS Endpoints Step Functions integration:

• https://aws.amazon.com/about-aws/whats-new/2023/11/aws-step-functions-https-endpoints-teststate-api/
• https://aws.amazon.com/blogs/aws/external-endpoints-and-testing-of-task-states-now-available-in-aws-step-functions/

Use Case

CDK should support the HttpInvoke Step Functions integration, so it can be managed via IaC.

Proposed Solution

Task should allow specifying all standard, optional, and required parameters (endpoint, HTTP method, EventBridge Connection ARN, headers, body, query string, etc.).

@MathieuGilbert hey there, do you already use this with a workaround? would also love to contribute somehow as I desperately need this construct :D

Hi @boringContributor, we aren't using this yet, but have plenty of Lambdas doing this manually which we'd love to replace. I have an initial implementation of this, I just need to find the time to test & polish it, hopefully this coming week.

@boringContributor Just wanted to update you as I've made some progress and have a WIP draft PR here. I tested it out by copying the construct to an existing project and it works if the Connection is set up right. It can be used that way if you don't want to wait for it to make it into the library. The only internal import can be hard-coded as Resource: 'arn:aws:states:::http:invoke'.
