As a web-rca user I want to get message before handover so I am reminded.

This will need db migration: add `team_handovers`

• team_id (UUID)
• timezone (e.g., America/New_York)
• list of times (e.g., ["08:00", "13:30", "17:45"])
• pause (toggle button) - handover can be paused `/rca handover pause`
• automatic_pause (set of days: monday - sunday)
• paused_by (text: user/automatic) - so we know if the pause should be resumed or not.
• Create logic around the times from `team_handovers` to automatically create new notifications. I would suggest use new `go routine` in web-rca/servecmd/cmd.go `func runServe`
  • Something like followUpWorkerServer - handoverWorkerServer

Automatic handovers:

• Ping Incident Owner to go through handover.

• Setting this notifications only from UI because we have Notification Subscriptions only as UI feature + this will be probably one time setup thing
• We will need add handover table I propose `team_handovers`
• We will send notification on `team_handovers` to the incidents (incident channels) where is `team`/are `teams` associated with
• Create `Handover` Notification. 
  • Pro: we can use notifications for sending emails and more in the future.
  • Con: We will have basically duplicated message in events and notifications
    • Notification has attribute `message`
    • Event has attribute `note`
    • Also Notification has event_id the purpose of this is:
      • We are sending this notification before creating handover (handover has to create Incident Owner manually) - That means event_id will not be used by our notification record.
