Is your request related to a problem? Please describe.

Currently the Cloudwatch log group is automatically created with a retention period of "Never expire". This is not ideal as it leads to unexpected costs.

Describe the solution you'd like.

In line with other terraform-aws-rds modules, it would be nice to specify the log group creation and retention period.

Describe alternatives you've considered.

• Manually changing the retention period. Not infra-as-code :(
• Add a aws_cloudwatch_log_group resource manually outside the module. Could lead to situation where the log group has been automatically created and the resource outside the module fails.

Additional context

It should be easy to add the functionality copy-paste from one of the other official modules to support this functionality.
