Update to upstream version '0.17.2'
with Debian dir cb682d738260a73e1a5c714e32fe464181268a21

This module's use of write_addition predated the introduction of reliable
writing in swh.journal; Since this introduction, the backfiller has been
flushing the kafka writer after writing each single object, leading to a 3x
measured slowdown on backfilling contents.

as this happens quite often and isn't an error.

migrate_extrinsic_metadata: add support for guessing the origin of more PyPI packages from filenames.

Because it makes a lot of get requests and doesn't handle failures,
it crashed often.

The metadata migration script kept crashing otherwise.

The next version of swh-journal will remove the default value.

Update to upstream version '0.17.1'
with Debian dir 1a06182f324d3f658eec3faac9d724b9c9776f3a

It complicates the signature and the code, and we don't have any use
for it currently.

1. rename branch_info to last_branch
2. exclude the last_branch from 'branches', so that:
   a) it never needs to contain a None value, so we don't need a cast
   b) no need for slicing

Consistently with the new name for this attribute in swh.model 0.7.2.

For consistency with swh.model v0.7.2, to prepare for the addition of
an (intrinsic) id field to RawExtrinsicMetadata objects.

To match the new behavior of package loaders.

The old attribute was deprecated in swh.model 0.7.2

swh.model.model.ModelObject.compute_hash was changed to a method instead of a
staticmethod.

migrate_extrinsic_metadata: Make pypi_origin_from_filename fix project names when possible using PyPI's API.

Instead of bloating handle_row, which is already way too long.

migrate_extrinsic_metadata: add support for guessing the origin of more PyPI packages from filenames.

It now supports all pypi revisions with an id starting with an hex digit
from 0 to 5.

This is actually what starts the server, so it sounds more reasonable to test
that part.

This also drops the type parameter from load_and_check_config which is never
used.
