> A new Cache for per-disk db handles after rocksdb-merge.
> Originally we have the ContainerCache for per-container db handles.
> And we should have a new DatanodeStoreCache for per-disk db handles which should be relatively small.
>  
> We could choose whether to use the  DatanodeStoreCache or the ContainerCache according to the schema version in BlockUtils.getDB().
