Update to upstream version '0.7.3'
with Debian dir 52148284bb73fc33b424821f1624f3f539a5e6d3

This avoids throwing the deprecation warning when id and target are present and
have the same value, which makes a from_dict / to_dict round-trip throw no
deprecation warnings.

Update to upstream version '0.7.2'
with Debian dir 3d28dbc49bced19e4411f3c3f60af57d08510a4a

This backwards-compatible change prepares the transition to give
RawExtrinsicMetadata an `id` field that is computed intrinsically from its
contents (using the HashableObject mixin).

This will enable a gradual enhancement of the functions in identifiers.py to
take model objects directly, and return the bytes of the hash instead of an
hex representation.

This collapses the shared logic between these two identifier computations into a
few more explicit steps:
 - generate data for the manifest (in either identifier computation);
 - format the manifest (in the new format_manifest function);
 - hash the manifest (in the new hash_manifest function).

This will enable reusing this logic for more object types, as well as stronger
typing for the manifest computation.

Update to upstream version '0.7.1'
with Debian dir 7e580ad70508156c42e6cc2a3b98a9d95aee1a5a

that returns a value suitable for unicity constraints.

Motivation:

* this is somewhat more of a model concern than a journal/kafka
  concern IMO
* this is one step toward adding support for non-model objects in
  KafkaJournalWriter

Implementation of the unique_key methods comes from
`swh.journal.serializers.object_key`.

I created one in the wrong directory and didn't see the existing one.

Update to upstream version '0.6.7'
with Debian dir ff33196235173497970db1401a7c8d6ad3f8d9ce

The addition of '-p no:pytest_swh_core' in pytest.ini is needed to
prevent pytest from loading the pytest_swh_core plugin which we do not
need here and which would require some more dependencies (e.g.
requests).

Use the new SWHID naming convention instead of SWH PID.
