Add settings retry attempts and interval retry attempts for recurring snapshots

### The required feature described as a wish

We are facing a problem with recurring snapshots for volumes. When a recurring snapshot job fails, ACS keeps making endless retry attempts.

The user does not receive any notifications when a recurring snapshot job fails. Only repeated retry attempts to create the snapshot are observed.

In our test case, we reproduced the issue with an error:
```
Error while creating entity for allocating snapshot
```

It would be good to have the ability to configure:
- the of retry attempts
- the interval between retries

To avoid an infinite snapshot creation loop that ends with an error. After the maximum number of retries is exhausted, a notification should be sent informing that the job has failed.

Issue ではファイルやテストが特定されていません。まず、定期的に実行される snapshot job と、既存の retry および通知の経路を追跡し、次に設定のエントリーポイントを特定してください。retry 回数に上限があり設定可能であること、retry 間隔があること、retry を使い切った後に失敗通知が行われることを満たせば完了です。
