feat(analytics): add `smart_retries` only metrics

## Proposed changes

There should be fields in PaymentDistribution, for the case where we only want to extract metric for Subsequent smart retried attempts.

For example, we have `success_rate` and `success_rate_without_retries`

Now missing field is `success_rate_with_only_smart_retries`.

This change should be extended to all fields
