From: Royce Lv <lvroyce@linux.vnet.ibm.com>

Add interfaces to report existent volume group on host. the returning detail will include what pool this volume group belongs to. If this VG is not used by any storage pool, its storage_pool will be empty string. So the process of creating pool on existent VG will be: 1. List VG not occupied by storage pool: GET /host/vgs?storage_pool='' This will retrieve volume group path and user can choose from one.

I'd suggest to use 'pool' instead of 'storage_pool', just to make it simpler

2. Create storage pool from chosen VG: POST /storagepools/ {'path':volume_group_path, 'name': storagepool_name, 'type': 'logical', 'devices':[]}
