      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"
      		 
      }}
