Aggregated Css & js assets are not uploaded to s3

I have tested this module and noticed that specified bucket root (root folder) is not always good option. For example, if you need to store something out of public access on the same bucket, like private files etc. So, I made a minimal version that really takes the most logic from s3fs and Drupal system with a minimal changes.

Another thing related to fact that assets:// scheme does not managed by s3fs module, so the second patch s3fs-assets-support-3461756-2.patch is recommended to make it work.

I can't be 100% sure that everything work well, I'm in active testing process at moment.

Does not work at all.
Even after applying both patches and following instructions on README.
Site attempts to load assets from local file system and not S3.
