Cron based External API Connections are not executed if they are in an error state.
currently we don't have a way to report to subdomain admins ( users who have indicated they want to be emailed error messages) when cron based External API Connections have encountered critical errors (that prevent them from being run again).
The solution is to create a job that gets enqueued when a Cron based External API Connections are errored out.
This job sends an email to admins. We have to make sure admins are only notified once.
