Bug Description

On every create_volume there are two additional calls made to the backend, one to collect the volume_info which is needed, the other is for the cluster_info which doesn't change with every create_volume, hence that info can be cached on driver load.

self.cluster_vip = self._cliq_get_cluster_vip(cluster_name)

Minor optimization in create_volume in HpSanISCSIDriver

    Removing extra call to getClusterInfo in HpSANISCSIDriver
    on every create_volume call. The cluster info is now
    being lazily stored in a local variable.

Fixes bug 1074201
