Zap lambda: Migrate to reading grouped requests (URL's) via Job id

[mohdnr]

JOB_Id which is the same for all of the URLs from a given request. So we can tie all of the things that are run from a given request together.

I am trying to figure out if job_id should be scan_id or a template_id from #9 instead

I'm going to add some comments to #9 as it needs to be updated slightly I think.

Actually, nm, I think job_id would be scan_id ...

[mohdnr]

scan_id & report_id's are being used to group results.
