Delete empty assets directories

Problem Statement

DotCMS accrues empty directories like assets/a/7/a7fea5fe-bed3-478b-890e-d56984d97e97 - presumably for deleted FileAssets but I'm not sure of this.

The number of empty directories runs often runs into the millions. These empty dirs add hours to the time required to clone filesystem data. Cloud Engineering manually deletes empty directories before cloning filesystems which itself is a slow process.

The Clean-bin-and-file-assets Tool does not appear to remove these directories.

Steps to Reproduce

for folder in 0 1 2 3 4 5 6 7 8 9 a b c d e f; do find assets/$folder -maxdepth 2 -type d -empty -ctime +0; done | wc -l

Start by locating the Clean-bin-and-file-assets Tool and checking how it handles filesystem cleanup. Use the provided find command against assets directories to reproduce the problem, then verify that the implementation prunes empty asset directories without affecting non-empty directories.
