Bulk update file links

[AntoninCrestois]

When uploading files in the File manager and using a specific domain to generate links to those files used in webpages, there is no easy way to replace those links in pages if we decide to use another domain down the line.

The only option currently is to manually go into each page and edit the direct links to those files.

Here's a quick example of this:

Initial domain: www.abc.com

All my files become linked with www.abc.com/hubfs/12356etc

I change domains to www.123.com but the file on my webpage doesn't update accordingly, instead it still directs to www.abc.com/hubfs/12356etc. 

This can make the change tedious for people with multiple pages and or modules that utilise those file links.
