List the OLEDB providers
                List the OLEDB providers available in the system by using the GetOleDbProviders method.
Example
The handle of the request is -1 because the GetOleDbProviders method applies at global level.
The client sends:
{
  "jsonrpc": "2.0",
  "id": 0,
  "method": "GetOleDbProviders",
  "handle": -1,
  "params": []
}
                        The engine returns:
{
  "jsonrpc": "2.0",
  "id": 0,
  "result": {
    "qOleDbProviders": [
      {
        "qName": "SQLOLEDB",
        "qDescription": "Microsoft OLE DB Provider for SQL Server"
      },
      {
        "qName": "MSDataShape",
        "qDescription": "MSDataShape"
      },
      {
        "qName": "SQLNCLI11",
        "qDescription": "SQL Server Native Client 11.0"

      {

      },
                              ...
                              {

        "qDescription": "Microsoft OLE DB Enumerator for SQL Server",
