backups: Implement scheduled backups

This MR proposes simplified approach for scheduling backups:

• Each repository is assigned to exactly one schedule. Schedule can be disabled (default).
• There are only three periods for backup: daily, weekly and monthly. Each can be disabled.
• Backups are cleaned up automatically based on return values.
• Borgmattic a backup scheduler for Borg was considered and rejected. Provided value is not worth the integration effort.
• Notifications are shown for errors and to encourage a new user to setup a backup schedule.

Update fixes pylint import related failures.

Seems like enabling a schedule should automatically dismiss the notification.

Two changes:

• I have added code to dismiss the notification when a schedule is enabled.
• The name of the scheduled backup archives was not changing unless the list of periods changes. This leads to Borg rejecting the schedule backup for the second time for same list of periods. So, I appended the time stamp to the name of the archive to fix this.
