Add support for custom responses for more rules, such as size_constraint_statement_rules

[maggie-weber]

Describe the Feature

When manually configuring WAF rules, users can configure custom responses for rule types like size_constraint. The Terraform resources on which this is based also seems to support this, but the configuration hasn't been extended out to this module.

The field is already configurable for rule_group_reference_statement_rules.rule_action_override.custom_response and managed_rule_group_statement_rules.rule_action_override.custom_response.

Expected Behavior

The custom_response block that already exists should be extended to other rule types where it is support by AWS and the underlying Terraform resources.

Use Case

I would like to provide a contextual error message to consumers of my API when the request size is too large.

Describe Ideal Solution

The custom_response block that already exists should be extended to other rule types where it is support by AWS and the underlying Terraform resources.
