Creating new storage instances as persist. in ONE

Storage created in the ONE backend should always be persistent.
Its behaviour now resembles that of an ordinary block device.

`console_link` is no longer implemented in the backend, it should
not be declared in the model.

Mixins from http://opennebula.org/occi#infrastructure should be
included before instantiation, not just upon re-parsing.

from the model once the collection leaves the backend.
