TS-4627: support TSRemapOSResponse in ts_lua
@jpeach pls take a look. Thanks.
I want to add enhancement to ts_lua so I can write script to take advantage
of the TSRemapOSResponse() related functionality.
Basically it would allow me to do something when origin server fails to
connect (such as DNS error, timeout, etc)
