Expose resource ARN for AWS API Gateway Stage

[chendilv]

Current Terraform Version

Terraform v0.12.2

Use-cases

A WAF WebACL can be associated with an API Gateway Stage. This is supported by terraform already : https://www.terraform.io/docs/providers/aws/r/wafregional_web_acl_association.html
However, terraform does not provide a way to access the resource arn for a API Gateway Stage : https://www.terraform.io/docs/providers/aws/r/api_gateway_stage.html

(The execution Arn is something different - the API Gateway Stage Arn will have the format arn:aws:apigateway:{region}::/restapis/{api_id}/stages/{stage_name})

So there is no (clean) way to provide a API Gateway stage resource arn to a WebACL association.

Attempted Solutions

Proposal

Add an attribute called 'arn' to aws_api_gateway_stage that exposes the resource arn of the API Gateway stage.

This would make it a lot easier indeed. I just stumbled on this in trying to figure out how to build the stage arn for WAF

We really need this. It makes much easier when applying a WAF to an API gateway, not having to generate the ARN for the API

The arn attribute will be added as part of #10570

Support for the arn attribute has been merged and will release with version 2.36.0 of the Terraform AWS Provider, Thursday next week. Thanks to @DrFaust92 for the implementation. 👍
