TerryHowe b3335b3474 Do not set default versions in parsed args
Setting default versions in parsed args makes it so OCC
cannot tell if the argument was parsed, an environment
variable was set or it is just defaulted.  In order to
set api versions from OCC, it will have to be defaulted
after processing OCC.
