Add support for aws/cloudformation

[radeksimko]

This may sound a bit silly as CF & TF are two competing products with similar functionality, but it is imo not.

As there's support in the new aws library we recently started using, I was thinking this could be a great chance to allow users to run/update/delete CF templates from terraform, which could make any transition from CF to terraform much more smooth.

Example of a new resource:

resource "aws_cloudformation_template" {
  on_failure = "ROLLBACK"
  parameters {
    firstKey = "first-value"
    secondKey = "second-value"
  }
  stack_name = "sample-name"
  template_body = "${file(cf-templates/my-stack.json)}"
}

Eventually having the templating functionality at some point, Terraform could completely replace both cotdsa/cumulus & cloudtools/troposphere which I've seen people using to work around issues that CloudFormation has.

This actually makes sense to me. Terraform shouldn't discriminate against an AWS API because it seems to compete. Terraform should be able to managed all IaaS, PaaS, SaaS so interfacing with allowing you to CRUD CloudFormation makes sense.

+1 as TF could work as a wrapper and glue language around existing CloudFormation setups which opens it to more potential users.

+1, this would make the transition from those huge, impossible to maintain CF templates a lot easier and safer.

+1, There are few resources for which I am writing CF templates(because terraform doesn't support them), it would be great if I could use terraform to manage CF templates.

Hey folks - we're consolidating Requests for AWS resources over in the spreadsheet linked at #28 - head over there to record your username on what you'd like us to prioritize next!

For people that come to this from google, this was implemented in #2636. Nice job @radeksimko!
