Well, I failed the challenge to release it before new 2018 year. But later is better than never!

Detail are boring, you'd better look at examples in README!

1. All the server-info-* utils have one entry point now.
2. Old server-info-rate and server-info-show utils deleted.
3. server-info-collect called via wrapper until it will be rewritten in python. It's a separate issue.
4. Added (and fixed) tests for server-info --rate feature. It doesn't fail on all examples in ./tests/server-info-show.test/
5. Yes, utils call looks like this now: server-info --rate instead of server-info-rate
6. You can collect data and optional pack it into tarball with server-info --directory <path-to-directory> --gzip. It will make <path-to-directory>.tar.gz with all the data that you can take from server for later analyze.
7. New examples are already in README.
