auto-pause: make time to pause configurable

[medyagh]

we need to add extra flag into start command because, we don't have any flag not exists for addon's option. so is it right?
How about use --addon-config with {addon_name}.{key}={value}
e.g.)
minikube start ..... --addon-config=auto-pause.time=10s

FWIW there is also configure inside of minikube addons but for configuring at time of enabling I think you are right and a new flag would be needed like --images. --images is used like minikube addons enable <x> --images=image:a,image:b,image:c

I don't know if this would belong as an argument to minikube start though, as the add-on isn't installed by default AFAIK
