• For CLI args, I thought we were using all lower case? I see some are camel case and others are not.
• Did not verify args correctness. Once we have a base set of common args then different permutations of those would apply depending on specific API.

We will use camelCase. QnAMaker CLI is already using camel case. All lower case is not readable. It would have been best if we were case insensitive (and I hope we get there).
