title: Is there any way to clean/delete some older packages in helm repo?
body: <p>We've setup an AWS s3 storage as Helm repo.</p>
  
  <p>But with development going on, more and more package files are uploade to the S3.</p>
  
  <p>We want to cleanup/delete older files in S3, of course, I know we can't directly delete them from S3 as there're some mapping info stored in index.yaml.</p>
  
  <p>I check the <code>helm help</code>, got few information about this. Is there any formal way to delete older helm packages?</p>
