A trivial stateless slack bot that notifies about new broken tests in ClickHouse CI.
It checks what happened to our CI during the last check_period hours (1 hour) and
notifies us in slack if necessary.
This script should be executed once each check_period hours (1 hour).
It will post duplicate messages if you run it more often; it will lose some messages
if you run it less often.
You can run it locally with no arguments, it will work in a dry-run mode.
Or you can set your own SLACK_URL_DEFAULT.
Feel free to add more checks, more details to messages, or better heuristics.
It's deployed to slack-bot-ci-lambda in CI/CD account
