Sending mail with configurable content on success, warning, error

Current Situation

• Mail is sent directly from JobScheduler on specific events as on_success, on_error, on_warning.
  • Events and recipients are configured in factory.ini
• The content of mails can be configured by modifying the stylesheet scheduler_mail.xsl.
  • This is a somewhat tough task and requires good XSLT knowledge and thorough testing.

Desired Behavior

• Sending mail is considered to be out-tasked from JobScheduler to a new Plugin:
  • Develop a separate component in Java
  • make use of the Plugin Interface as indicated by JS-1195
• Basic functionality
  • authentication
  • encrypted communication
  • formatting of mail content
  • queueing of outgoint mail (as covered by the housekeeping job scheduler_dequeue_mail)
  • support for distribution lists
• Usability
  • Better configurability for individual conditions when to send mail.
  • Better manageability of mail contents and recipient groups
• Operability
  • Better control of the point in time when mail is sent (at job start, at end of job)
