Support remote file systems such as S3

Attaching a patch against 2.0.0 release version. It's not clear to me what the latest working branch is (2.0.x vs 2.x). While 2.x has the latest commit, it is missing a commit from 2.0.x (https://git.drupalcode.org/project/media_thumbnails_video/-/commit/9472f...).

2.0.x is branch under development. 2.x has a wrong branching name but I can't remove it.

2.0.x is branch under development.

OK, sounds good. I will create MR against 2.0.x.

Separately, you might need to cherry-pick https://git.drupalcode.org/project/media_thumbnails_video/-/commit/66b09... from 2.x to 2.0.x.
