Some origins are listed as urls while they are not. They are possibly vcs. So this
commit tries to detect and and deal with those if possible. If not possible, they are
skipped.

The end goal is to ingest sparsely the origins, that would avoid hitting the various
servers around the same time for colocated origins in the upstream manifest (especially
file or tarball).

In listers collecting artifacts for each package to load, add artifacts
checksums, when that info is available, in parameters sent to loaders
in order to check downloaded artifact integrity.

'artifacts' extra_loader_arguments should be a list

Prefer to execute lister through a celery task as it also enables to
catch possible issues with task implementation.

Also use docker compose v2 commands.

The base lister class now ensures the count of listed origins will
be accurate.

Previously, the run method was returning the total count of ListedOrigin
objects sent to scheduler database.

However, some listers can send multiple ListedOrigin objects for a given
origin URL during the listing process, for instance when an origin is
contained in multiple pages (e.g. gogs listing) or when the listing
is gathering multiple versions of an origin spread across multiple
pages (e.g. maven listing).

This changes ensures an accurate count of listed origins by maintaining
a set of origin URLs associated to the sent ListedOrigin objects.

The puppet lister retrieves origins from from https://forge.puppet.com/modules

Use http api point to get package names and build origin urls.

With the extension, the readme is included in the swh-docs build and fails. It's not
intended for the documentation build so renaming it keep it out of the doc build loop.

This fixes build [1].

That HTTP header value will now contain the lister name but also a link
to our contact form in order for sysadmins to easily reach us if needed.

The following template is used to generate it:

"Software Heritage <lister_name> lister v<swh-lister version>
 (+https://www.softwareheritage.org/contact)"

Numerous listers were using the same page_request method or equivalent
in their implementation so prefer to deduplicate that code by adding
an http_request method in base lister class: swh.lister.pattern.Lister.

That method simply wraps a call to requests.Session.request and logs
some useful info for debugging and error reporting, also an HTTPError
will be raised if a request ends up with an error.

All listers using that new method now benefit of requests retry when
an HTTP error occurs thanks to the use of the http_retry decorator.

Instead of retrying HTTP requests only for 429 status code by default,
prefer to use the generic retry policy enabling to also retry for status
codes >= 500 but also on ConnectionError exceptions.

Rename throttling_retry decorator to http_retry to reflect this change.

For some forges, the default tab for a repository detail is not the
summary tab so the clone urls are not detected and the repository
is ignored

This also affects the gitea lister

Align with other lister names by turning it to lowercase.

It ensures created temporary directories will be removed once they
are no longer needed.

This matches other lister verbosity.

Use a value that matches good practice recommended by pub.dev REST API doc.

https://github.com/dart-lang/pub/blob/master/doc/repository-spec-v2.md

In order to get a last_update for each ListedOrigin sent to scheduler
database, send an extra HTTP request for each listed package to the
/api/packages/<package_name> endpoint of pub.dev API.

A pub.dev developer inform us that endpoint is heavily used and cached
so there is no particular issues to query that endpoint for each package
in a row periodically.

Use https://pub.dev/packages/<package_name> instead of
https://pub.dev/api/packages/<package_name>

It will enable to archive the history of the PKGBUILD file associated
to the AUR package.

Use https://aur.archlinux.org/packages/<package_name> instead
of https://aur.archlinux.org/<package_name>.git

Simplify code for downloading packages index as gzip and deflate
transfer-encodings are automatically decoded by requests, also
do not stream response for a couple of megabytes and store
HTTP responses in memory.

Also add more debug logs to track lister execution.

This uses https://index.golang.org. An associated loader will be sent in
the near future, as well as an incremental version of this lister.
