Currently, we log initial sync metrics while the initial sync is running but discard once the initial sync is finished.

In order to have a better understanding of the initial sync performance for our customers, we should preserve this information after the initial sync is complete.

We can use log ingestion on 4.2 and earlier clusters to keep the initial sync metrics in our current logs to begin.
