This brings over the work done by @apparentlymart and @radeksimko in
PR #3124, and converts it into a data source for the AWS provider:
This commit adds a helper to construct IAM policy documents using
familiar Terraform concepts. It makes Terraform-style interpolations
easier and resolves the syntax conflict between Terraform interpolations
and IAM policy variables by changing the latter to use &{...} for its
interpolations.
Its use is completely optional and users are free to go on using literal
heredocs, file interpolations or whatever else; this just adds another
option that fits more naturally into a Terraform config.
This data source allows one to look up the most recent AMI for a specific
set of parameters, much like aws ec2 describe-images in the AWS CLI.
Basically a refresh of hashicorp/terraform#4396, in data source form.
This commit adds a data source with a single list, `instance` for the
schema which gets populated with the availability zones to which an
account has access.
