Add support for individual e-mail recipients of notifications about job execution results

Feature

• Notifications by mail are managed by the Resources->Notifications view.
  • This includes to specify global recipients of e-mail notifications by use of the To, Cc, Bcc attributes.
• Users would like to specify recipients of notifications on a per job basis.
  • This includes to overrule recipients specified by the configuration that is managed from the Resources->Notification view.
  • Instead To, Cc and Bcc recipients can be specified per job.
• If mail recipients are specified by a job then this overrules Notification settings.
  • No merge of configuration items for mail recipients applies.
• Rules when to send e-mail:
  • the folder, workflow or job has been configured with the CONFIGURATION -> Notification view to send e-mail.
    • Job Notification settings:
      • empty - e-mail will be send if configured by CONFIGURATION -> Notification recipients.
      • 'Mail on' is empty (Mail To or Cc or Bcc is not empty)
        • Mail is not sent as no event is selected for triggering, this can be used to suppress e-mail from being sent.
      • 'Mail on' is not empty (Mail To is empty)
        • Mail is not sent as no recipient is specified
      • 'Mail on' is not empty but does not correspond to the configured CONFIGURATION/Notification type
        • Mail is not send as the Configuration -> Notification settings not to send e-mail overrules the Job Notification settings. This can be used to centrally suppress e-mail from being send.

Implementation

• This feature requires changes of
  • the Inventory API,
  • the GUI to add notification types and mail recipients from an additional tab "Notification" of a job,
  • the Monitor Service to use mail settings on a per job basis if available.

Maintainer Notes

• This feature is intended for compatibility with branch 1.x of JobScheduler.
