Failover to alternative iSCSI portals on login failure

Registered by Tomoki Sekiyama on 2014-11-11

When the main iSCSI portal is unreachable by network failure etc., volume attach/detach will fail even though the other portal addresses is reachable. To enable nova-compute to fall-back to alternative portal addresses, cinder should tell the alternative portal addresses to nova.
