Checkpoint two changes:
1. Using frisbee events in libosload_new as a replacement for statically (hand waved) maxwait times for image loading. When frisbee is generating events, we use those to determined if progress is being made. 2. Convert the CM to using the libosload_new library directly (like os_setup does). This is conditional on the NewOsload feature being attached to the geniuser. Otherwise, we go through the old path.
