dm vdo: add the block allocators and physical zones

Browse source 
Each slab is independent of every other. They are assigned to "physical
zones" in round-robin fashion. If there are P physical zones, then slab n
is assigned to zone n mod P. The set of slabs in each physical zone is
managed by a block allocator.
