Feature: Notification support and handling.

App will notify users in case of the following events:

- Node is connected or disconnected.
- A new node is added.
- Node is removed.
- Received new sharing request.
- Sharing of devices is accepted or declined.
- Any alerts from node.

Notifications are saved locally to be displayed in notification screen.

Device parameters are also updated instantly when app will receive an event.
