      Description

      The benchrun.py script defaults to --readCmd=false as seen in the mongoebench-compatible JSON config file with "readCmd" : false.

      benchrun_embedded/testcases/queries_identity_view_int_id_find_one.json

      ...
      "writeConcern" : { "j" : false },
      "writeCmd" : true,
      "readCmd" : false } ] }
      

      This causes DBClientConnection::findOne() to be called rather than DBClientConnection::runCommand() being called via runQueryWithReadCommands(). Legacy OP_QUERY reads do not support views - only the "find" command does. Changing the mongoebench-compatible JSON config files to be generated with --readCmd=true would address this issue.
