Merge ~troyanov/maas:power-activity-retry-policy into maas:master

[Anton Troyanov]

fix: set maximum attempts for power activity

We don't want Activities to be retried forever.

> Maximum number of attempts. When exceeded the retries stop even if not expired yet.
> If not set or set to 0, it means unlimited, and rely on activity ScheduleToCloseTimeout to stop.
