[PATCH 2/2] post_pw: Store submitted checks locally as well

Jeremy Kerr reports that our PW checks reporting submitted 43000 API calls
in just a single day. That is alarmingly unacceptable. We can store the
URLs we've already submitted and then just skip over any additional
processing at least on the PW side.
This patch does two things to try and mitigate this issue:
1. Store each patch ID and URL in the series DB to show that we reported
the check. This means we don't need to poll patchwork for check status
2. Store the last modified time of the reports mailing list. This means
we only poll the mailing list when a new email has surely landed.
