Anton Arefiev c5c2d67b7f Find resource refactoring
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.
