Update reports automatically on Agora

Summary:
Rhyne-Wyse is a bot based on pywikibot to update pages on the wiki
for automated reports.

It can use the code from nasqueron-reports tool, the same run-report uses,
to generate a report for ressources reachable from a standard server.

For resources less easily accessible, it can also fetch a report
already generated by run-report on a remote URL, as implemented
in D3674 for AI content from DevCentral databases.

It's not intended to run as a daemon like an IRC bot, but to be run
at regular intervals, for example daily.
