Update to upstream version '0.0.52'
with Debian dir 95c5716132b2b4cd84b3f5a5dd75bb25bf9f3654

Add support to automatically compute identifier in the following object models:
Directory, Release, Revision, Snapshot.

If the identifier is not provided as parameter, it will be computed when the model
is initialized.

Allows us to call tests on things other than python3, with the same settings.

they will remain for internal use only, so should not be mentioned in this
public spec

currently provides mainly 2 generators:
- gen_origins()

we do not really need them to be mutable, plus we gain their instances now
being hashable, so we can add them in set() for example.

with Debian dir 2751e4653a1b0de8dab5bc1ba1b7583d4c722b5d

Instead of relying on attr.asdict recursion, we do recursion ourselves. This
simplifies a lot of the inherited to_dict() methods.
