Bug Description

This is a "sub-bug" of https://bugs.launchpad.net/mos/+bug/1509398

With "iscsi_use_multipath=true", detaching a multipath iSCSI volume kills all iSCSI volumes visible from the attached node. When we use different targets(IQNs) associated with same portal for each different multipath device, all of the targets will be deleted via disconnect_volume().

This patch fixes the behavior of detaching volume:
  1. Extract the targets for the detached multipath device.
  2. Delete/disconnect the targets for the detached multipath device.

Same issue as in bug #1521648. In Kilo Nova uses its own code to provision volumes. It is needed to patch nova/virt/libvirt/volume.py file to change the way it operates.
