f5736f3178 block-device lvm: fix umount phase 
As described in blockdevice.py detachment and (most) resources
release must be done in the umount phase of a block device module.

Until now these jobs were done in the lvm cleanup() phase - which
is too late - especially when using nested LVMs.

This patch moves the functionality of the cleanup() phase to the
umount() phase for the lvm module.
It includes a test case that fails without applying the provided
source code changes.

bb6cf52d85 Remove dd from LVM element 
This patch removes the unneeded dd calls in the lvm block device
plugin.

After removing the underlying block device, there is the need to call
'pvscan --cache'.  This is done by a dedicated LVM cleanup node which
is cleaned up after the the underlying block device.
