Add cutoff repos and counts to error message

[robertbrignull]

The queries API is changing so that it won't fail when you try to run a query on more than 1000 repos. Instead it'll cap the repos off at 1000 and tell you in the response which repos weren't queried (up to a limit of 100 repos).

This PR is for handling that change in the API and display the information in the log message. While there I also updated the log message in general to include the counts of the repositories in the various states. I think this makes it more consistent if we're including the count for the cutoff repositories case.

Any input on the wording of the log message is very welcome. Writing these messages is very hard 😢

Messages look good to me!

This looks great 👍

I've left a suggestion, but feel free to ignore it as I think the way we do message building is fine.

[elenatanasoiu]

Since we're building a log message from:

• two end of lines
• a number
• a message
• another eol
• a list

in three separate situations, extracting those lines into a method might improve readability.

e.g.

logMessage += buildCutOffMessage(private_repositories, "repositories are not public");

let buildCutOffMessage = (list, message) => `${eol2}${list.length} ${message}:${eol}${list.join(', ')}`;

I like this suggestion but I think I'll just get the PR merged first so I can get this and the API change done today. Then potentially come back to this and see how it works out. Definitely the potential to make the area more understandable, but also could spend a lot of time messing with it.
