Admin preview images are by default postfixed with a cacheRef to disable browser cache

Bug report

Describe the bug

Uploaded images in the Amin are postfixed with a cacheRef value to disable browser cache.

At the moment there is no option to enable / disable this postfix from the Media Library settings, however, in the code there is (sometimes) a property available (but this one is always set to true).

I would like to load my images using a CDN (CloudFront) but this postfix makes my signed-urls invalid. Therefore i'm unable to display them properly.

Steps to reproduce the behavior

1. Sign urls with CloudFront in the File-model lifecycle(s)
2. Go to Media Libary and try to preview the image
3. The preview image won't be displayed

Expected behavior

When the fileCache is disabled (if possible) then it should display the preview image correctly.

System

• Node.js version: v14.16.0
• NPM version: 6.14.11
• Strapi version: 3.5.3
• Database: Mysql
• Operating system: MacOS

Additional context

If we could make the file-cache configurable in the Media Library > Setting then we can apply this setting in the necessary components. I can't access my files directly in S3 due to company restrictions so I always need to use the CDN to fetch them.

@derrickmehaffy I tested with v.3.6.2 but this does not make a difference
