Support scope-down statements

[mikstew]

Describe the Feature

Update the module so that is supports scope-down statements for managed rule groups and rate-based rules.

https://docs.aws.amazon.com/waf/latest/developerguide/waf-rule-scope-down-statements.html

Expected Behavior

Accept scope_down_statement within rate_based_statement_rules and managed_rule_group_statement_rules, like the following:

module "waf" {
  source = "../.."
  
  rate_based_statement_rules = [
    {
      name     = "rule-40"
      action   = "block"
      priority = 40

      statement = {
        limit              = 100
        aggregate_key_type = "IP"
      }

      scope_down_statement = {
        matches = {
          request_components = {
            uri_path = "/path"
          }
        }
      }

      visibility_config = {
        cloudwatch_metrics_enabled = false
        sampled_requests_enabled   = false
        metric_name                = "rule-40-metric"
      }
    }
  ]
}

Use Case

We would like the module to support more WAFv2 functionality so we can continue to use it.

Describe Ideal Solution

It would be great if this module supported scope-down statements.

I was able to create an aws_wafv2_rule_group with a scope-down statement outside of this module and assign it to the web ACL using rule_group_reference_statement_rules. It may be nice for the module to support scope-down statements directly in the rate_based_statement_rules, but the work around is more than adequate so I will close this request. Thanks!
