Merge lp:~stevenk/launchpad/destroy-pppd into lp:launchpad

[Steve Kowalik]

Destroy the process-pending-packagediffs cronjob, its tests, the model code it used, and the horses they rode in on.

Destroy the process-pending-packagediffs cronjob and friends, now it is no longer needed due to the switch to the job system.

-"""Process pending PackageDiffs.
-
-Process a optionally limited set of pending PackageDiffs.
-
-By default it process up to 50 diffs each run, which is enough to catch
-up on 1 hour of uploads (on average).
-
-However users might benefit for more frequently runs since the diff ETA
-relative to the upload will be shorter.
-
-The cycle time needs to be balanced with the run time to produce the shortest
-diff ETA and to not overlap much, for instance, if it has to diff monster
-sources like openoffice or firefox.
-
-Experiments with the cycle time will be safe enough and won't sink the host
-performance, since the lock file is exclusive.
