[Spike] investigate the impact of AWS EFS hardlink limits

[yolabingo]

Problem Statement

AWS EFS has a very modest limit of "177 hard links to a file." DotCMS makes extensive use of hard links. The impact of this EFS limit is unknown. What does dotCMS do when it cannot create a hard link?

Cloud Eng often encounters hard link-related errors along the lines of "too many hard links" when trying to copy data using tools like rsync or AWS Data Sync. It is not clear if these errors are related to the EFS limit or not.

We see files on EFS that have 177 hard links. Plausibly, some of these files "should" have more hard links.

Steps to Reproduce

Unknown to me, I'm not sure when or how dotCMS generates hard links.
