Implement error notifications for the automated script

[guiweber]

It would be nice to be notified when broken rules are detected when the fully automated script runs. Possible solutions:

• Email: Require additional config and credential storage when deploying the script.
• OS Notifications: Simpler, no credentials/configuration necessary. (https://github.com/mikaelbr/node-notifier). Need to test if notifications are persistant and can be made to be non cummulative (we only want the notification from the latest script run to be displayed). May take a while to see the notification in comparison to other more direct solutions.
• SMS: Require additional config and credential storage. Free solutions may not be viable.

• For email, I usually use sparkpost.
• There could also be self-hosted push notifications or a web-based status page.
• For sms, there is the free (limited plan), or the self-hosted version of textbelt: https://textbelt.com/

A chatbot for Slack or Telegram would also work - both require an account, but in Telegram you could a Channel where the Bot could announce updates to the registry without people spamming. Or you could subscribe to it. I would willing to build such a beauty.

@Schokobecher That's something I had not considered. Would you be able to make a Gitter chatbot? Not sure what API/functionality Gitter offers, but since were using it for our dev chat it would be good to have it there. We could add a channel for updates and one for errors and you can subscribe to the channel you're interested in.
