It may still work, but the reality is probably that nobody knows.

- Python 3.9.2 is the default version of Python in current Debian oldstable.
  The current Debian stable (12, Bookworm) has already 1 year (june 2023).
- CubicWeb 4.5.2 was published at the end of 2023.

We would have liked to upgrade more.
However the new minimum versions are the ones of an active project.

Version 3.24.9 previously used does not exist and 3.24.7 is the latest
one available at the moment.

This implementation provides an S3Storage that can be used to store entities
attributes in an Amazon S3 storage.

It comes with an STKEY rql function to be able to retrieve the S3 object key
for the entity attribute (similar to BFSS's FSPATH rql function).

S3 connection configurations are attached to the S3Storage instance, like:

  s3_storage = S3Storage(s3_bucket)
  storages.set_attribute_storage(repo, 'File', 'data', s3_storage)
