commit 9f8ddea7d00964ec6c0b3e61e3d02882ea380f1f
Author: Xiaochu Liu <xiaochu@chromium.org>

optionally mount image loading a component

Add a bool parameter |mount| in Load API. It allows developer to control
whether to mount the image or not after component is installed.

I also add an alias for LoadCallback to increase readability.

BUG= chromium:797140 
TEST=call Load API with true/false.
