      Downstream Change Summary

      This patch makes changes to the slow query log line as well as the serverStatus counters. It also changes the system.profile collection, which will have identical fields to the new slow query log line. This change will also be backported to 5.2.

      Description of Linked Ticket

      Add a field that indicates whether we used classic or SBE for a query. We should backport it to 5.1. At the least we want to see how many queries are exposed to SBE.

      Worth considering:

      • just logging a field if the less common case happens (e.g. "sbe")
      • should we use the same field in the future for the optimizer (e.g. "sbe" (executed with sbe) / "cqf" (optimized and executed with cqf)
