rocksdb allows to open in readonly mode

See #678

rocksdb read only mode cannot sync with the write, secondary db instance doesn't work well either, if we cannot find a very useful and elegant solution, then I think we can abandon this

the whole point is to have 1 R/W + n R instances and the n read instances can sync well with the write
