This patch implements creating iSCSI storagepool for libvirt. Each LUN in iSCSI storagepool can be used as a volume, but iSCSI storagepool does not provide ability to create volume. For now in kimchi we create volume for each newly created VM. Next is to implement attaching existing volume to a new VM.

How to test

Create: curl -u root -H 'Content-type: application/json' \ -H 'Accept: application/json' \ -d '{"srcTarget": "targetIQN", "srcHost": "10.0.0.X", "type": "iscsi", "name": "iscsipool"}' \ http://127.0.0.1:8000/storagepools

Show Info: curl -u root -H 'Accept: application/json' \ http://127.0.0.1:8000/storagepools/iscsipool

Activate: curl -u root -H 'Content-type: application/json' \ -H 'Accept: application/json' \ -d '' http://127.0.0.1:8000/storagepools/iscsipool/activate

Examine: iscsiadm -m session

Deactivate: curl -u root -H 'Content-type: application/json' \ -H 'Accept: application/json' \ -d '' http://127.0.0.1:8000/storagepools/iscsipool/deactivate

Delete: curl -u root -X DELETE -H 'Accept: application/json' \ http://127.0.0.1:8000/storagepools/iscsipool
