This patch improves the handling of storage information before and after a call to the RPC 'node_info'. It adds a function to not only call for all storage information on the cluster (as it is used right now), but to ask only for storage information for a particular disk template. This way, in many cases, for example by the iallocator, less information is requested and thus performance is increased. Unit tests are provided.
