Report out "unconfigured"/"unknown" projects.

Is your feature request related to a problem? Please describe.

With the way things are handled currently we report out:

• An overall summary, to a "default" channel
• Individual team summaries to the team channels

Any repository where the owner(s) cannot be detected spit out a warning to the console, and then their reports are dropped. We should be doing something with these instead. With some of the recent refactors, I did bucket these all together in the reports, we just don't do anything with them yet.

Describe the solution you'd like

A report should be specifically designed and formatted to report out these homeless findings. Probably something to go to the "default" Slack channel. Definitely some kind of summary.

I'm not so sure this is strictly true anymore. With all of the changes for multiple data sources, we no longer do this "bucketing". But I think it's still fairly easy to discover projects which are not owned. Their Owners map will simply be empty. So it should be easy enough to loop through all projects in a ProjectCollection, check for an empty Owners map, and report out on matching ones.
