Column order function

__Proposal:__
Need a function to order columns manually.

__Current behavior:__
Table columns are received in a specific order and cannot be changed

__Desired behavior:__
InfluxDB 2.0 result table columns could respect function keep() column order and return results columns in that order

|> keep(columns: [“inventory_no”,“temp1”,“temp2”,“battery1”,“rssi”])

__Alternatives considered:__
Alternatevy there could be specific column order (priority) function.

__Use case:__
GUI respects columns order received from InfluxDB?
