Merge lp:~stevenk/launchpad/kill-rpsd into lp:launchpad

[Steve Kowalik]

Remove cronscripts/rosetta-pofile-stats-daily.py and the horse it rode in on.

cronscripts/rosetta-pofile-stats-daily.py is unnecessary, has not been run for quite a while, interferes with FDT if it does want to get run, and has been replaced by a job. Delete it, with prejudice.

[Curtis Hovey (sinzui)]

Thank you.

review: Approve (code)

-been modified in the last week (or whatever number of days is configured
-in rosetta_pofile_stats.days_considered_recent parameter).

-
-We add two POFiles with incorrect statistics, with one of them last
-modified 8 days ago, and another recently modified.
-
-    >>> now = datetime.now(pytz.UTC)
-    >>> more_than_a_week_ago = now - timedelta(pofile_age + 1)
-    >>> pofile_recent = removeSecurityProxy(factory.makePOFile('sr'))

-A run of `VerifyRecentPOFileStatsProcess` script fixes only the POFile
-which was modified in the last week.

-We can see that stats have been updated in the recently touched POFile,
-but not in the older one.
-
-    >>> pofile_recent.rosettacount
