Public bug reported:

When a volume is detached from a VM on Hyper-V, the Nova driver tries to
disconnect from the iSCSI target, even if it's in use.

https://github.com/openstack/nova/blob/master/nova/virt/hyperv/volumeops.py#L194

This make sense when a volume (LUN) is associated with only one iscsi
target, but this isn't always the case, you can have only one iSCSI
target that exports more than one LUN to the hypervisor.

We could provide a general solution that will only disconnect from the
iSCSI target when there aren't more disks exposed to the hypervisor.
