rDLSf57b8f3a2c49: cpan: Improve listing process by querying the metacpan release endpoint
Summary

Instead of querying the metacpan distribution endpoint to list origins,
prefer to use the release endpoint instead enabling to list all artifacts
associated to CPAN packages by scrolling results.

Compared to previous implementation, it enables to compute a last_update
date for all CPAN packages but also to obtain artifact sha256 checksums
that will be used by the CPAN loader to check downloads integrity.

It also enables to save a call to metacapan Web API in cpan loader as all
needed info about package artifacts are now provided as extra loader
arguments.

Related to T2833

When testing this in docker, I could list all CPAN packages and their
artifacts in less than 4 minutes.

Rebase and update cpan lister:

  • process all pages from CPAN API before sending origins to scheduler
  • add extrinsic metdata URL for each module version and send it to cpan loader
  • miscelleaenous code improvements

    cpan: Improve listing process by querying the metacpan release endpoint

    associated to CPAN packages by scrolling results.
    
    Compared to previous implementation, it enables to compute a last_update
    date for all CPAN packages but also to obtain artifact sha256 checksums
    that will be used by the CPAN loader to check downloads integrity.
    
    As the multiple versions of a module are spread across multiple pages
    from the CPAN API, origins are sent to the scheduler once all pages
    processed, it is also faster to proceed that way.
    
    Also compute extrinsic metadata URL for each perl module versions in
    order for the cpan loader to query it.

easier to read, IMO

I'd rather pass the BASE_URL and let the loader build this URL; it will allow changing loader behavior without changing the lister too.

Ok but this means I have to add the release name in module metadata, not a big deal though.
