SDK : Add support for RAW in the SDK for N1QL queries

Doesn't look like we are supporting RAW as a part of the SDK - Query interaction,

This works -> select count from `inv_skuinventory`

This doesn't -> select  RAW count from `inv_skuinventory 

I understand the failure reason, however from a supporting N1QL standpoint I believe we should address the RAW keyword. There might be places where customers use it.
