VGN Locator (EU): Easier way to diagnose errors

A customer requests that there should be an easier way to diagnose errors in Locator.

For example, when a job, such as print, dxf-export, or create dynamic document, fails in process manager, the admin currently receives an e-mail stating that the job has failed. The actual error message is contained in the logs of the process manager pod. This error message should be directly included in the error e-mail.

In a production environment, the admin receiving the e-mail will likely not have access to the Kubernetes service or the knowledge to work with those logs. Many simple problems such as typos in dynamic documents could already be resolved if the error message is forwarded.
