(rds): ServerlessClusterProps is missing copyTagsToSnapshot

[SydneyUni-Jim]

Describe the bug

DatabaseClusterProps.copyTagsToSnapshot exists but ServerlessClusterProps does not have this property.

The CloudFormation documentation does not suggest that this doesn't apply to Aurora Serverless.

Expected Behavior

This compiles

new rds.ServerlessCluster(scope, id, {
  copyTagsToSnapshot: true,
  engine: rds.DatabaseClusterEngine.auroraMysql({ version: rds.AuroraMysqlEngineVersion.VER_2_07_1 }),
  // …
})

and generates a CFT with

  DBCluster:
    Type: AWS::RDS::DBCluster
    Properties:
       CopyTagsToSnapshot: true
       Engine: aurora-mysql
       EngineMode: serverless
       EngineVersion: 5.7.mysql_aurora.2.07.1
       # …

Current Behavior

A TypeScript error that ServerlessClusterProps does not have copyTagsToSnapshot.

Reproduction Steps

Try to copyTagsToSnapshot: true to the props when creating a rds.ServerlessCluster.

I can't find anything that says that it is not available for serverless either.

This issue has been classified as p2. That means a workaround is available or it is deemed a nice-to-have feature. Given the amount of work there is to do and the relative priority of this issue, the CDK team is unlikely to address it. That does not mean the issue will never be fixed! If someone from the community submits a PR to fix this issue, and the PR is small and straightforward enough, and meets the quality bars to be reviewed and merged with little effort we will accept that PR. PRs that do not build or need complex or multiple rounds of reviews are unlikely to be merged and will be closed to keep our backlog manageable.

In the mean time, remember that you can always use the escape hatch (https://docs.aws.amazon.com/cdk/v2/guide/cfn_layer.html) mechanism to have fine control over the CloudFormation output you want. We will keep the issue open for discoverability, to collect upvotes, and to facilitate discussion around this topic.

We use +1s on this issue to help prioritize our work, and are happy to re-evaluate the prioritization of this issue based on community feedback. You can reach out to the cdk.dev community on Slack (https://cdk.dev/) to solicit support for reprioritization.
