Creating 10+ dynamo tables now causes LimitExceededException

[hashibot]

This issue was originally opened by @grayaii as hashicorp/terraform#16525. It was migrated here as a result of the provider split. The original body of the issue is below.

---

Terraform Version

Terraform v0.10.7

Terraform Configuration Files

resource "aws_dynamodb_table" "tab1" {
    name           = "${var.environment}_cron"
    read_capacity  = "${var.cron_read_capacity}"
    write_capacity = "${var.cron_write_capacity}"
    hash_key       = "task_arn"
    attribute {
      name = "task_arn"
      type = "S"
    }
}
resource "aws_dynamodb_table" "tab2" {
    name           = "${var.environment}_cron"
    read_capacity  = "${var.cron_read_capacity}"
    write_capacity = "${var.cron_write_capacity}"
    hash_key       = "task_arn"
    attribute {
      name = "task_arn"
      type = "S"
    }
}
// ETC ETC... all the way up to 15 tables.

Expected Behavior

Dynamo tables should have been created without throwing a LimitExceededException, and without terraform failing.

Actual Behavior

 * aws_dynamodb_table.change_in_condition: AWS Error creating DynamoDB table: LimitExceededException: Subscriber limit exceeded: You have exceeded the maximum number of indexed tables that can be created simultaneously
 	status code: 400, request id: BJLQQ32VNNT0C3SF1OJ28ES3QFVV4KQNSO5AEMVJF66Q9ASUAAJG
 * aws_dynamodb_table.cron: 1 error(s) occurred:

 * aws_dynamodb_table.cron: AWS Error creating DynamoDB table: LimitExceededException: Subscriber limit exceeded: Only 10 tables can be created, updated, or deleted simultaneously
 	status code: 400, request id: 2HBQDGSJJQ2740DD08G9KPF8GJVV4KQNSO5AEMVJF66Q9ASUAAJG
 * aws_dynamodb_table.es_wotc_pay_period: 1 error(s) occurred:

Steps to Reproduce

1. terraform init
2. terraform apply

This only started happening when we upgraded terraform from v0.8.8 to v0.10.7. It seems to be that terraform is creating all the tables in parallel, not sequentially, or at least it's failing now where it used to work before.

This PR should hopefully fix this up: #2274
