[Enhancement]: Support RetainExceptOnCreate for aws_cloudformation_stack

[lorengordon]

Description

AWS added a new option RetainExceptOnCreate option to the CreateStack API, and a few other related operations. I would like to be able to set this option when creating/updating a stack with Terraform. The attribute is not currently exposed by the resource aws_cloudformation_stack (according to its docs).

Affected Resource(s) and/or Data Source(s)

• aws_cloudformation_stack

Potential Terraform Configuration

resource "aws_cloudformation_stack" "example" {
  ...
  retain_except_on_create = bool
}
