title: AWS EFS - lifecycle rule to delete old files
body: <p>I'm using EFS</p>
  <p>I want to set up some form of lifecycle rule to delete all files that are in the EFS for over 10 days (or preferably, but not necessary, if they were not accessed for 10 days)</p>
  <p>From the configuration, it seems not to be possible. Is there some way to do that? Maybe using some lambda or something else?</p>
