Disk Layout change: Make vdev_info 4KB to allow upgrade needs #137
Description
We need also to add version into vdev_info structure.
The issue is raised here instead of homestore because nuobject2 is already released and this new change will be for nublox 2 and before we release, we need to make this change and only take effect after HomeStore version say 6.x, by the time this change is being made.
There will be an if branch in code to allow this new change to format the disk on first time boot.
