[aws-ec2] VPC FlowLogs to S3 Bucket with Subfolder

[relm923]

Add optional support for setting subfolders when declaring S3 bucket as destination for VPC Flow logs

Use Case

AWS Documentation

Setting subfolders allows buckets to be reused for multiple purposes

Proposed Solution

Add optional subfolder argument to FlowLogDestination.toS3() to allow for defining bucket prefix.

Other

If LogDestinationType is s3, specify the ARN of the Amazon S3 bucket. You can also specify a subfolder in the bucket. To specify a subfolder in the bucket, use the following ARN format: bucket_ARN/subfolder_name/. For example, to specify a subfolder named my-logs in a bucket named my-bucket, use the following ARN: arn:aws:s3:::my-bucket/my-logs/. You cannot use AWSLogs as a subfolder name. This is a reserved term.
