Support for background jobs out of the box

[Mexxerio]

I like carrierwave, but the lack of good background job support is a big downside, since processing images in a background task is a very common use case. The only gem available for this is carrierwave-backgrounder, but this gem hasn't had a new release since 2015 and is not really maintained anymore.

It would be a huge plus if we could get official background job support out of the box which is being maintained properly.

I now switched over to ActiveStorage because of that

I would definitely love to see this as well. Currently my application processes small files which only take a few seconds to process, but anything over 10 MB causes quite a delay. What I would like to see in this feature request:

1. Toggle "process in background" for all files of a specific uploader class
2. Toggle "process in background" for specific uploads meeting some criteria (i.e. file size over 10 MB, image exceeds certain dimensions, etc.) - should take a block to execute per file uploaded

This would enable people to decide whether or not they want to push processing to a background task or not depending on their use case, even at a file-specific level.

I would like this as well. I'm currently still using Carrierwave v1, because carrierwave_backgrounder doesn't support v2
