Resumption of SubscribeVehicleData with several data items

[GetmanetsIrina]

According to current requirements for SubscribeVehicleData with several data items SDL must resume the list of data in one SubscribeVD request, but in proposal https://github.com/smartdevicelink/sdl_evolution/blob/master/proposals/0190-resumption-data-error-handling.md this requirement is redefined.

So there are 2 ways to cover the resumption of SubscribeVehicleData with several data items within handling of the errors from HMI:

1. According to current requirements SDL will resume SubscribeVehicleData with several data items with all data in one request like in
   
   and SDL will check general code of SubscribeVehicleData response and also each internal result code for each data.
   In case general code will be SUCCESS but some internal resultCode will be not SUCCESS (e.g VehicleInfo.SubscribeVehicleData( code:0, gps:{ dataType = VEHICLEDATA_GPS, resultCode = SUCCESS }, speed: { dataType = VEHICLEDATA_SPEED, resultCode = VEHICLE_DATA_NOT_AVAILABLE })) SDL will fail the resumption and will revert all data for current app.

2. According to proposal SDL resumes VD data in separated SubscribeVehicleData requests, each request for the resuming of one data item and in this case SDL will check only general resultCode:
   

What behavior is preferable for you?

We propose to use and implement the behavior according to current requirements (item 1)
