      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"
}}
