Alert for failed CronJobs

1. Proposed title of this feature request

Included alert for failed CronJobs

2. What is the nature and description of the request?

Customer is running CronJobs and would like to be alerted when a CronJob fails. Customer would like to see an overview of CronJobs where the last run of the CronJob (respectively the Job created by the cronjob) failed.

If the CronJob then executes again and the run succeeds, then the alert should be cleared again and no longer fire.

3. Why does the customer need this? (List the business requirements here)

Customer does not get notified if the last run of a CronJob was not successful. When counting the number of failed jobs, this does not take into account if the CronJob ran successfully afterwards. Failing jobs can have a direct impact on the customers applications and thus business, this should be monitor-able.

4. List any affected packages or components.
