    features/shard: Make o-direct writes work with sharding

    With files opened with o-direct, the expectation is that
    the IO performed on the fds is byte aligned wrt the sector size
    of the underlying device. With files getting sharded, a single
    write from the application could be broken into more than one write
    falling on different shards which _might_ cause the original byte alignment
    property to be lost. To get around this, shard translator will send fsync
    on odirect writes to emulate o-direct-like behavior in the backend.
