blk/kernel: add plugin system for devices with compression and move VDO support into plugin
The current VDO support implementation is buried inside the common/blkdev.cc
with a simple interface used by KernelDevice. It is not easily extendable
and can not be easily used for other devices providing similar capabilities.
This patch adds a plugin system that is based in its structure on the
erasure code plugin system and moves the VDO support code into a VDO plugin.
