provider/aws: feature request: Add a aws_sns_topic_permission resource

[keymon]

What

Lambda functions have a resource lambda_permission to allow grant permissions to resources to invoke them.

We need the same for SNS, which behaves and exposes similar API the methods than lambda: AddPermission and RemovePermission.

Example

resource "aws_sns_topic_permission" "with_cloudwatch" {
    statement_id = "AllowPublishFromCloudWatch"
    action = "Publish"
    topic_name = "${aws_sns_topic.example.name}"
    principal = "events.amazonaws.com"
    source_arn = "${aws_cloudwatch_event_rule.console.arn}"
}

Hi @keymon
we have support for aws_sns_topic_policy since 0.7.3 (September 5, 2016) which does pretty much what you described.

Do you agree we can close this issue now or do you have any specific use case that isn't covered by that resource?

Yes, ofc.
