Support for yaml api body

[tibbing]

It would be nice if we could also support yaml format API body. Currently doing the jsonencode(..) here restricts us to only providing a OpenAPI map:

terraform-aws-api-gateway/main.tf

Line 13 in d11aaba

body = jsonencode(var.openapi_config)

But aws_api_gateway_rest_api actually accepts a yaml string just as well. I.e. the following works:

data "template_file" "swagger_api" {
  template = file("./swagger.yaml")
  vars = {
    ...
  }
}

resource "aws_api_gateway_rest_api" "this" {
  count = local.enabled ? 1 : 0

  name = module.this.id
  body = data.template_file.swagger_api.rendered
  tags = module.this.tags

  endpoint_configuration {
    types = [var.endpoint_type]
  }
}

The easiest solution would probably be to just remove the jsonencode() part and let the caller do that if needed. Optionally we could add another variable instead for backwards compatibility.

Another upside to getting rid of the jsonencode is supporting the case where the caller already has the body as json, for example when reading a json file.

I'm able to do...
openapi_config = yamldecode(file("${get_terragrunt_dir()}/vars/infra1-io.yaml"))
I export from aws as a yaml formatted file.

Not your request, but could help in the meantime?
