Description
Currently we use ceph config to retrieve min_alloc_size for block device.
This value should be persisted, so even stand-alone ceph-bluestore-tool could operate properly.
There are 2 flavours of min_alloc_size for block:
1) the AU size that is used by core BlueStore
2) the AU size that is used by BlueFS to hold files when allocating from block.
Both should be part of superblocks info.
