vdo: add vdoimport support
Add tool 'vdoimport' to support easy conversion of an existing VDO manager managed
VDO volumes into lvm2 managed VDO LV.
When physical converted volume is already a logical volume, conversion
happens with the VG itself, just with validation for extent_size, so
the virtually sized logical VDO volume size can be expressed in extents.
Example of basic simple usage:
vdoimport --name vg/vdolv /dev/mapper/vdophysicalvolume

Version 2.03.13 -
===============================
+ Add vdoimport tool to support conversion of VDO volumes.
Support configurable allocation/vdo_pool_header_size.
Fix handling of lvconvert --type vdo-pool --virtualsize.
Simplified handling of archive() and backup() internal calls.
