Report issues to curators

[karolina-siemieniuk-morawska]

It would be good to have some mechanism to collect and report warnings from automated tasks to curators, so they can investigate and fix them, for example:

• HAL push failures
• Collaboration normalization
• Ambiguous reference matches

Idea: we could write to the logs in some specific format and have a separate process extract the data from the logs and send it somewhere (RT, zulip, etc.), either in real time or periodically.
