HP LeftHand CLIQ proxy may return incorrect capacity values

[Jim Branen]

The HP Lefthand CLIQ proxy may return incorrect total_capacity_gb, and free_capacity_gb values if there are more than one cluster configured in the management group. The call to getCluster in _update_backend_status should include the cluster name.

    Fix volume stats with multiple LeftHand clusters

    When more than one cluster exists in a LeftHand management
    group, get_volume_stats may return the stats for the wrong
    cluster. This patch fixes the problem by listing the cluster
    name in the getClusterInfo query.
