[WIP] provider/aws: Availability Zone helper resource

[pgray]

This resource reads the availability zones available to your account and provides a way of passing them to other resources/modules.

Example config:

resource "aws_availability_zones" "test" {
  name = "test"
}
output "az1" {
  value = "${element(aws_availability_zones.test.availability_zones, 0)}"
}

I'm looking for feedback on whether other people think this would be valuable, and hopefully guidance on how to test this better.

I'm thinking that it could save people time/lines of configuration when it comes to modules and other resources you might want 1 or more of across all your availability zones.

Hi @pgray! Thanks for opening a pull request! I completely agree that being able to get this kind of information from AWS is useful, and we definitely want to support it in Terraform. One thing we are currently working on is @apparentlymart's proposal of data resources in #4169 - the work is on PR #6598, which I am planning to review next week. With that in mind, I'm going to hold off merging this until that work is integrated - we will definitely implement this feature though!

Hey @jen20, thanks for the great feedback. I'll make sure to keep an eye on how things are going with that. I'd love to rework it once the changes are made to support data resources.

Hi @pgray, I've implemented this as a data source in #6671 as part of the review process. I used your code from the Read method here almost verbatim, so thank you for the PR! I'll close this in favour of #6671 for now.

Hey @pgray, yeah, I actually submitted pretty much the same thing as #4848 a few months ago. I think @apparentlymart is looking into rolling this feature and #4396 into the data sources feature once it's in.

Ahhhhhhh! Gotcha. Thanks all.
