Fixes bug 970406 - pull ADI/blocklist pings from Hive with crontabber

This job fetches ADI aggregates daily from Hive using a SQL query. Many thanks to @peterbe and @lars for help with the mocking, which proved to be daunting.
This needs to become:
```
if os.path.isfile(raw_adi_logs_pathname):
    os.remove(raw_adi_logs_pathname)
```
The reason is that something could go wrong on line 122 and then the file was never created.
