[performance] add optional S3 object info caching (#4546)

This adds an optional S3 object info cache to the S3 storage driver backend (see [here](https://codeberg.org/gruf/go-storage/releases/tag/v0.4.0)) to reduce S3 calls largely during media cleanup operations, but it should also help in other situations cutting back on S3 calls when for example a key is already known to not exist.
