Peter Dillinger 9fa5c146d7 LOG more info on oldest snapshot and sequence numbers (#10454) ... Summary: The info LOG file does not currently give any direct information about the existence of old, live snapshots, nor how to estimate wall time from a sequence number within the scope of LOG history. This change addresses both with: * Logging smallest and largest seqnos for generated SST files, which can help associate sequence numbers with write time (based on flushes). * Logging oldest_snapshot_seqno for each compaction, which (along with that seqno info) helps us to determine how much old data might be kept around for old (leaked?) snapshots. Including the date here I thought might be excessive. I wanted to log the date and seqno of the oldest snapshot with periodic stats, but the current structure of the code doesn't really support that because `DumpDBStats` doesn't have access to the DB object.
