Increase storage driver visibility for Filesystem

Description

Currently, storage drivers have very limited logging in place. It would be helpful to have a level of logging that would enable us to log requests and responses from the underlying storage system (where applicable), for example.

This would have allowed us to arrive at the cause of this issue: #341 (closed) quite a bit sooner.

There has been some effort here: !8 (merged), but not a unified approach.

Proposal

Add logging for container registries using Filesystem for object storage so that we can identify issues and resolve them faster and more efficiently.
