Correct syntax for Ipopt and JuMP request?

[greg_plowman]

Any of these seem to work:

model = Model(() -> Ipopt.Optimizer(print_level=0))

model = Model(with_optimizer(Ipopt.Optimizer, print_level=0))

model = Model(optimizer_with_attributes(Ipopt.Optimizer, "print_level"=>0))

I’m not sure if there is a preferred way?
