Add a URL suffix setting

Is your feature request related to a problem? Please describe.

Add a URL suffix option in settings. So that the URLs of uploaded files can be appended some more contents like query strings.

In my case, I use Alibaba Cloud OSS, an S3-compatible service. It provides an image processing function, in which I can define image processing rules (to add watermark, compress, etc.) and append a query string like ?x-oss-process=style/<rule name> after the image URL to get a post-processed image. I can also serve processed images only and disable access to the original image.

For example, if I uploaded an image to OSS and get the URL https://static.my.site/image.jpg, I can use the URL https://static.my.site/image.jpg?x-oss-process=style/forum to apply a image processing rule named forum to the image. It also provides a shorter way to add that post-processing rule like this: https://static.my.site/image.jpg/forum.

Describe the solution you'd like

Add an option in the extension settings so I can set a suffix to the URLs in the database.

Describe alternatives you've considered

Since I am not familiar with setting up a development environment and fear of breaking things, I just changed the code manually in my installation.

In file vendor/fof/upload/src/Adapters/AwsS3.php:

...
protected function generateUrl(File $file)
{
    ...

-   $file->url = sprintf('%s/%s', $cdnUrl, Arr::get($this->meta, 'path', $file->path));
+   $file->url = sprintf('%s/%s?x-oss-process=style/forum', $cdnUrl, Arr::get($this->meta, 'path', $file->path));
}
