YADE CredentialStore should use the attached file without intermediate storage in the local file system

Current Situation

• At run-time YADE can export the file included with the attachment field of a Credential Store database to the local file system.
• Current configuration is complex an use several settings elements:
  • CSExportAttachment
  • CSExportedFile
  • CSKeepExportedFileOnExit
  • CSOverwriteExportedFile
  • CSPermissionsForExportedFile
• This situation also poses a potential security risk if the exported file can not be deleted after the transfer

Desired Behaviour

• YADE should use the CreadentialStore attachment as a byte stream instead of temporary file
• Usage of the configuration CS... elements (see above) is no more supported (starting with the JobScheduler version 1.12.1)
• CreadentialStore field referencing
  • <AuthenticationFile>cs://mypath@attachment</AuthenticationFile>
    • the first attachment (KeePass file formats 1 and 2)
  • <AuthenticationFile>cs://mypath@my_custom_field_attachment</AuthenticationFile>
    • a specified attachment (KeePass file format 2)
