Goden Yao resolved HAWQ-462.
----------------------------
Resolution: Fixed
final fix is to use querycontext to pass on the security token as well as the
key in Hash table (key is in the format of "protocol://<host><port>").
So pxf (as external table) is using the same code path to handle secured
environment query with tokens as native tables.
