This unifies with other lister tasks modules. And this allow the cgit task to
be scheduled by the add-forge-now scheduler cli.

Some URLs of the repositories endpoint from BitBucket REST API 2.0
can return an error 500. In that case, skip the buggy repositories
page and get next one to continue listing and avoid to end it
prematurely.

This fixes python 3.7 support due to poetry, a dependency of isort, that
removed support for that Python version in a recent release.

requests_ratelimited fixture from swh-core was renamed to
github_requests_ratelimited.

remaining_requests parameter was added to the github_response_callback
function from swh-core, making it no longer compatible with requests_mock
callback for json responses.

In order to remove warnings about /apidoc/*.rst files being included
multiple times in toc when building full swh documentation, prefer to
include module indices only when building standalone package documentation.

Also include them the proper sphinx way.

Hopefully one day we'll be able to replace all of this mess with PEP692
TypedDict kwargs, but that's only on track for Python 3.12.

Some GitLab instances use specific namespaces for transient repositories
that it doesn't make sense to archive (for example, gitlab.org has a set
of QA namespaces used for integration testing of their production
deployments; drupal has an `issues/` namespace with forks of repos that
are only used for collaboration on merge requests, and aren't that
useful to be archived).

This cuts down one more manual step in the add forge now validation
process: we can add the relevant origins to the staging scheduler
without enabling them at all.

This will allow more automation of the staging add forge now process:
for known-good listers, we can limit the number of origins being
processed and reduce the amount of manual steps taken for each instance.

The SQL dump contains ownership instructions that can't be run if you
don't have the right users in your database clusters. When someone has a
psqlrc with ON_ERROR_STOP, this fails the load of the dump.

Use the opportunity to trigger an exception when psql returns a non-zero
exit code, rather than continue with an empty/inconsistent database.

In a similar way to the debian lister, use the following versions in the
packages dictionary provided to the generic rpm loader:

- dict keys are package versions prefixed by the fedora release and
  edition they have been found (fedora{release}/{edition}/{version}),
  they will be used as branch names targeting releases in the snapshot
  created by the rpm loader

- version fields in dict values are the package intrinsic versions parsed
  from package repository metadata excluding any ".fcXY" suffixes to avoid
  the loader to create multiple releases targeting the same directory,
  they will be used as release names in the snapshot created by the rpm
  loader

For consistency with Maven and Packagist listers

Deploying the nixguix lister, I realized that even though the credentials configuration
is properly set for all listers, the listers actually requiring github origin
canonicalization do not have access to the github credentials. It's lost during the
constructor to only focus on the lister's credentials. Which currently translates to
listers being rate-limited.

This commit fixes it by pushing the self.github_session instantiation in the constructor
when the lister explicitely requires the github session. Hence lifting the rate limit
for maven, packagist, nixguix, and github listers.
