Add recurring schedule for weekly batch scheduler job

Schedule the job to run every Monday at 2:15 AM London time. We tell
users that we will run the job shortly after 2:00 AM.

We're scheduling it to run a little while after the job to schedule
the daily batches has run in order to spread the load on the system.
