This change is about adding the ability to the OneView drivers of dynamically allocate OneView resources to Ironic. The current version of the drivers consider what we call "pre-allocation" of nodes, meaning that when a node is registered in Ironic, even if it is not in use, this resource is still reserved in OneView. This change will prevent such situations by allocating OneView resources only at boot time, allowing both systems to really share the same pool of hardware.
