(aws-kinesis): cfnguard reports incorrect rule name

What is the problem?

If you don't have a Redshift destination configured for a Kinesis Firehose, cfn-guard reports a KINESIS_FIREHOSE_REDSHIFT_DESTINATION_CONFIGURATION_USES_SECURE_PARAMETER violation, but to suppress the error you need to use what appears to be the name of a subRule(?). Whatever is going on inside the tool, you need to use KINESIS_FIREHOSE_REDSHIFT_DESTINATION_CONFIGURATION_NO_PLAINTEXT_PASSWORD to suppress the warning if no Redshift destination configuration exists.

BTW - the same incorrect behavior happens for Splunk destinations.

Reproduction Steps

Triggers the KINESIS_FIREHOSE_REDSHIFT_DESTINATION_CONFIGURATION_USES_SECURE_PARAMETER warning despite suppression:

          ":",

    }
   }

What did you expect to happen?

The reported error name should be the error that needs to be suppressed - you shouldn't have to go to the github repo to debug the actual name.

What actually happened?

A different error name has to be suppressed.
