SimpleChatTC:SimpleProxy:LoadConfig ProcessArgs cleanup - initial

Now both follow a similar mechanism and do the following

* exit on finding any issue, so that things are in a known
  state from usage perspective, without any confusion/overlook

* check if the cmdlineArgCmd/configCmd being processed is a known
  one or not.

* check value of the cmd is of the expected type

* have a generic flow which can accomodate more cmds in future
  in a simple way
