### Issue # (if applicable) Closes #30340. ### Reason for this change Current LustreFileSystem class does not support automatic backups. ### Description of changes Add properties equivalent to those of the L1 construct to the L2 construct. * [automaticBackupRetentionDays](https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws%5C_fsx.CfnFileSystem.LustreConfigurationProperty.html#automaticbackupretentiondays) * [copyTagsToBackups](https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws%5C_fsx.CfnFileSystem.LustreConfigurationProperty.html#copytagstobackups) * [dailyAutomaticBackupStartTime](https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws%5C_fsx.CfnFileSystem.LustreConfigurationProperty.html#dailyautomaticbackupstarttime) Segregated the `dailyAutomaticBackupStartTime` as a class to enable its usage in another file system's L2 construct (for example, Ontap) in the future. ### Description of how you validated changes Add unit tests and integ tests. ### Checklist - [x] My code adheres to the [CONTRIBUTING GUIDE](https://github.com/aws/aws-cdk/blob/main/CONTRIBUTING.md) and [DESIGN GUIDELINES](https://github.com/aws/aws-cdk/blob/main/docs/DESIGN_GUIDELINES.md) ---- *By submitting this pull request, I confirm that my contribution is made under the terms of the Apache-2.0 license*
