current version of S3 Storage cannot set url domain prefix

[pecasha]

Describe the solution you'd like

In previous versions it was possible to set a prefix, but when the Endpoint domain was different from the CDN domain, it was not possible to set a prefix which prevented the use of the CDN domain.

In fact, CDN image addresses only need to be spliced with URL Prefix and Filepath template, and do not need to using pre-signed url.

Additional context

If can't using CDN, some images are too large, take longer to load.
