os/bluestore/BlueFS: add bluefs_sync_write option

If we have a fast device we can do our writes using synchronous
IO instead of aio.  Most of the time rocksdb is doing sync writes
anyway (write and then fsync from the same thread).

Note that this might not be the case when using the
bluestore_sync_submit_transaction mode... that probably should
not be combined with bluefs_sync_write.
