Thanks for the feedback, Tom.
Regarding "primary binary" and "jar", to clear up confusion I'm just going
to call it "app jar" for now and if/when we add support for non-jar binaries we
can find something more suitable.
Regarding arg vs. args, I found the plural in args confusing - it makes it
seem like the parameter should take multiple values when in fact it takes a
single value and can be specified multiple times. Other parameters with
plurals, like "jars", don't work this way. We could possibly add --arg and
deprecate --args for the spark-class way?
