The 'name' field for some resources is called something different, for example 'display_name' for volumes, 'name' for volumes type. So class 'resource' has attribute 'NAME_ATTR' wich contains attribute name for different resources. This change removes reduntant call find in resource manager, instead of it checks NAME_ATTR value.
