[Findit] Flake Detection: Add false_rejection_count_last_week to Flake

Project Member Reported by chanli@chromium.org, Sep 6

Issue description

Add a field false_rejection_count_last_week to Flake to record number of occurrences detected for the flake for the past week.

To update the field, setup a cron job to run every few hours:
- Get all flakes that have occurred in the past week
- For each flake, count all occurrences that happened within past week, and use that as false_rejection_count_last_week


We may also add another field 'last_cron_time' to record the timestamp of the most recent update on the Flake entity by the cron job.
 
How are we going to extend this to support hidden flakes?
If we support other types of flake occurrence, we can add new fields for each count: I want the counts to be independent from each other so we can index them and query flakes accordingly.

And update the flakes with the counts in the same cron job. So last_cron_time can be just one.
Also add another field impacted_cl_count_last_week.
