Tags are not applied to api gateway resources

I've been tagging my resources, partly for billing, but also for access control. It turns out that the [`tags` property](https://aws.github.io/chalice/topics/configfile.html#tags) is applied only to the lambda functions and not to any of the additional resources such as the [api gateway](https://docs.aws.amazon.com/apigateway/latest/developerguide/apigateway-tagging.html).

This is found when being packaged to terraform but may also be the case for other deployment options.

chalice 1.26.2, python 3.8.0

Start with the `tags` configuration property and the Terraform packaging path, then compare how tags are applied to Lambda functions versus API Gateway and other generated resources. Confirm whether other deployment options are affected; done means configured tags reach API Gateway resources and the relevant deployment paths have coverage.
