Generate third-party snapshots and reports

[dav3r]

This PR updates extras/create_snapshots_reports_scorecard.py with the ability to fetch a list of third-party report organization IDs (via a newly-created report type "CYHY_THIRD_PARTY" - see cisagov/cyhy-core#35), then create snapshots and reports for those third-parties.

Notes:

• The snapshots that are created for third-parties use the --use-only-existing-snapshots flag, which means that the third-party snapshot will simply roll up the results from the latest snapshot for each child of the third-party org. This avoids the undesirable situation where an org gets one snapshot created for it's own report and a second snapshot created for the third-party report.
• The third-party reports are logged in the reports collection, just like regular customer CyHy reports are.
• I blackened create_snapshots_reports_scorecard.py, so you may find it easier to review these changes in the individual commits.

For additional details, refer to CYHYDEV-780.

Seems logical and well thought out. Nice work 👍 Just a couple minor quibbles.

Also I'm not sure if it's worth it, but I do wonder if we should do a pass at some point to make the string formatting methods uniform. The older code is using printf style and newer pieces (including what you've added) uses the str.format() style. Just something to consider.

I don't disagree with you @mcdonnnj, but I didn't want to spend any more time touching code that was unaffected by this change. Some things will just have remain ugly for now.

Approved. Just needs some info on that SSM thang.
