fix(query): added module support for "iam_db_cluster_auth_not_enabled" query

[cx-ricardo-jesus]

Closes #

Reason for Proposed Changes

• The query "IAM DB Cluster Auth Not Enabled" for the Terraform platform does not have support for the module that is equivalent to the aws_rds_cluster.
• Some cases are not covered by the samples in both CloudFormation and Terraform platforms.

Proposed Changes

• Created two more policies, the first one checks if the field iam_database_authentication_enabled is not defined, and the second one checks if the field is defined to false.
• Added module samples.
• Added more samples to the CloudFormation, also.
• Changed the second verification on the helper function for both query implementations.

🛠 Guidelines to remediate hardcoded secrets

1. Understand the implications of revoking this secret by investigating where it is used in your code.
2. Replace and store your secret safely. Learn here the best practices.
3. Revoke and rotate this secret.
4. If possible, rewrite git history. Rewriting git history is not a trivial act. You might completely break other contributing developers' workflow and you risk accidentally deleting legitimate data.

To avoid such incidents in the future consider

• following these best practices for managing and storing secrets including API keys and other credentials
• install secret detection on pre-commit to catch secret before it leaves your machine and ease remediation.
