Re: [Kimchi-devel] [PATCH 08/16] Move all resources related to storage pools to control/storagepools.py

From: Aline Manera <alinefm(a)br.ibm.com&gt; StoragePools(Collection), StoragePool(Resource) and IsoPool(Resource) were moved to a new - control/storagepools.py That way we can easily know where storage pool resource is implemented.
