Registered by

Nova currently uses many different methods for lazy loading components. These approaches should be unified, and a single standard method for lazy loading components should be adopted.

Whiteboard
Currently, nova uses at least four different methods for lazy loading components:
utils.load_object (managers and drivers)
utils.load_class (auth manager)
utils.LazyPluggable (db backend)
switch statement (virt connections)
All of them start with a flag. There is no reason to have four different ways of delayed object loading.
