Description
There are a couple problems that can affect our ability to troubleshoot state restore from changelog.
1. KeyValueStorageEngine logs a message for every 1M messages restored, but it doesn't print anything for smaller stores. We should add a message to report the final number of entries restored.
2. While the "restore-time" metric is a gauge, the KeyValueStorageEngineMetrics "messages-restored" and "messages-bytes" are both counters, and counters are often graphed in terms of deltas so the value disappears after one data point. Since these values only matter for the beginning of the job, we should switch them to gauges so the value is retained for later monitoring.
