    Introduce sysfs infrastructure for exofs cluster filesystem.

    Each OSD target shows up as below in the sysfs hierarchy:
    /sys/fs/exofs/_/devX

    Where _ is the unique identification
    of a Superblock.

    Where devX: 0 < device_table_size. They are ordered
    in device-table order as specified to the mkfs.exofs command

    Each OSD device devX has following attributes :
    osdname - ReadOnly
    systemid - ReadOnly
    uri - Read/Write

    It is up to user-mode to update devX/uri for support of
    autologin.

    These sysfs information are used both for autologin as well
    as support for exporting exofs via a pNFSD server in user-mode.
