Delete S3 bucket content before the publish

When amplify publish starts, it builds and uploads files to s3, but doesn't delete the actual S3 bucket content, so we end up after a month of updates with a bucket with over hundreds and hundreds of files,

**Describe the solution you'd like**
Before the Amplify uploads files, delete everything in the bucket.

**Describe alternatives you've considered**
i do aws s3 rm s3://bucket --recursive before the amplify publish -c
