add optional 2nd stage initialization to -object/object-add commands
Introduces USER_CREATABLE interface that must be implemented by objects which are designed to created with -object CLI option or object-add QMP command. Interface provides an ability to do an optional second stage initialization of the object created with -object/object-add commands. By providing complete() callback, which is called after the object properties were set. It allows to: * prevents misusing of -object/object-add by filtering out objects that are not designed for it. * generalize second stage backend initialization instead of adding custom APIs to perform it * early error detection of backend initialization at -object/ object-add time rather than through a proxy DEVICE object that tries to use backend.
