    Description

      For this task we just want to translate tests of modes "insertDocuments" and "replaceDocuments". Don't worry about removing duplicate coverage, that will be done by SERVER-41197.

      Written as   Translates to

      {$out: {
       to: "x",
       uniqueKey: \{x_id: 1},
       mode: "insertDocuments"
      }}

      {$merge: {
       into: "x",
       on: "x_id"
       whenMatched: "fail",
       whenNotMatched: "insert"
      }}

      {$out: {
       to: "x",
       uniqueKey: \{x_id: 1},
       mode: "replaceDocuments"
      }}

      {$merge: {
       into: "x",
       on: "x_id",
       whenMatched: "replaceWithNew",
       whenNotMatched: "insert"
      }}
