Implement a script for identifying repos that need issues or pull requests triaged

[jtauber]

I think the most generally useful thing for this script to do is show, for each repo, how many open issues and pull requests are in each Milestone (or don't have a Milestone). That way we can see, for example, how many issues haven't been triaged, how many are blocking a distribution, etc.
