      `$rename` cannot rename fields with dots (.) in their names:

      A collections like:

      > db.test.find()
      { "_id" : ObjectId("578ec46e39b3c19fbbeb2264"), "a.b" : 1 }
      { "_id" : ObjectId("578ec46e39b3c19fbbeb2262"), "a.b" : 2 }
      >
      

      won't get updated with:

      > db.test.update({}, { $rename : { "a.b" : "ab" }}, false, true);
      WriteResult({ "nMatched" : 2, "nUpserted" : 0, "nModified" : 0 })
      >
      > db.test.find()
      { "_id" : ObjectId("578ec46e39b3c19fbbeb2264"), "a.b" : 1 }
      { "_id" : ObjectId("578ec46e39b3c19fbbeb2262"), "a.b" : 2 }
      >
