Hello all,
I’m modifying  nova-scheduler, implementing my own scheduler;
there is a way to get all the list of the scheduler hints(for example when I lunch a new Instance, add a custom Hint MY_HINT, with value 100)?

I tried with 
 
def select_destination(self, context, spec_obj):
	…..
	spec_obj.get_scheduler_hint(‘MY_HINT’) # but it return None
	…..

thank you
