Set pre_start_required to false in get_device_plugin_options

What this PR does / why we need it:
Set pre_start_required to false in get_device_plugin_options to match the setting in register().

We set pre_start_required to false when akri instance device plugin registers itself to kubelet but kubelet still calls get_device_plugin_options to decide if to call device plugin's pre_start_container() In get_device_plugin_options(), we return true for pre_start_required so kubelet calls pre_start_container(). We don't expect the pre_start_container() to be called so we dump an error message and return empty option. Since we don't want the pre_start_container() to be called, we should set pre_start_required to false in get_device_plugin_options().

The impact is an unnecessary error message shown the might cause confusion.
