[Feature Request] API Gateway: Support for API Keys in Custom Authorizer Responses

[shalomvolchok]

In December, AWS announced the ability to provide the gateway api-key from a Lambda function. This allows for flexible options beyond only being able to set it with an x-api-key header.

I've been digging around to see if Terraform supports this, but pretty sure it doesn't yet. Seems like it would be here if it was: aws/resource_aws_api_gateway_rest_api.go

In the AWS UI it shows up under settings with two possible values. API Key Source: HEADER and AUTHORIZER. The feature works great for our needs and would be nice to be able to enable it with Terraform.

A new api_key_source argument on the aws_api_gateway_rest_api resource will be released with v1.22.0 of the AWS provider later this week 🎉

This has been released in version 1.22.0 of the AWS provider. Please see the Terraform documentation on provider versioning or reach out if you need any assistance upgrading.
