T2991: Port packagist lister to the new Lister API

Commits

rDLSff05191b7db7: packagist: Reimplement lister using new Lister API

Summary

The previous implementation was generating tasks for a non implemented
Packagist loader.

The new implementation extracts source repository URL, VCS type and
last update date for each package referenced by Packagist and send
those info to the scheduler.

Packages metadata are retrieved using Packagist API endpoints whose
responses are served from static files, which are guaranteed to be
efficient on the Packagist side (no dymamic queries).
Furthermore, subsequent listing will send the If-Modified-Since HTTP
header to only retrieve packages metadata updated since the previous
listing operation in order to save bandwidth and return only origins
which might have new released versions.

I tested intensively the lister yersteday and it worked without any
issues each time I executed it. First execution took around 90 minutes
and listed 286510 origins with three different visit types: git, hg and
svn. Subsequent calls took less time thanks to the If-Mofified-Since
HTTP header use and only returned packages modified since last listing.

Closes T2991

lgtm

But it's missing some coverage on conditionals (according to jenkins).

Maybe simply enrich the current test dataset with some of
those skipped packages in the current new dataset you added
(one bitbucket entry, another with missing origin_url, another
with missing time, etc...)

Ack, will improve coverage then.

Rebase and improve coverage
