Some back-ends support blocksizes other than the default 512 (like 4096),
this change adds a provider_geometry column to the volumes table,
format is "physical_block_size logical_block_size".
This can then be used by libvirt to determine if it should pass in
non-default block_size info, and there's a method for future
geometry/disk info that might be needed.
