    add bluestore-specific config options

    Adds bluestore-specific options related to the metadata-only journal.

    The options allow a user to control:

    1. path to a bluestore wal (block special file or regular file)
    2. path to a bluestore db (block special file or regular file)
    3. size of both

    Their configuration works similarly to the FileStore journal. If paths
    are not specified both WAL and DB will be collocated on the same block
    device as data.

    Other options can be configured via an existing config-flags option if needed.
