      Extend the update command to take an object or an array:

      {
   update: <collection>,
   updates: [
      { q: <query>, u: <update obj OR update pipeline>, upsert: <boolean>,
        multi: <boolean>, collation: <document>, arrayFilters: <array> },
      { q: <query>, u: <update obj OR update pipeline>, upsert: <boolean>,
        multi: <boolean>, collation: <document>, arrayFilters: <array> },
      ...
   ],
   ordered: <boolean>,
   writeConcern: { <write concern> },
   bypassDocumentValidation: <boolean>
}

      For this task, the only supported stages will be $addFields, $project, and $replaceRoot.

      For this task, we should ban other options such as 'collation', 'bypassDocumentValidation', 'writeConcern', 'arrayFilters'. All except 'arrayFilters' will eventually be supported, but will be tracked by separate tickets.
