Display new workflow feature on Features tab

We want this new "Workflow Management" feature to be displayed in the Features tab. 

• New entry "Tasks Management".
• Add it between document type selection and S3 lines.  
• Default is disabled.
• Explainer: 
  • Launch drive, by default "Tasks Management" is disable. No notification will pop-up
  • After launching drive, enable the feature. Drive will check for pending task and send system notification if any
  • In every 1 hour, drive will check for new tasks assigned between that duration and send notification if any
  • Disable feature, no notification will pop-up
  • Enable feature->Quit drive and launch it again, drive will check for pending task and send notification if any.
