exofs: Add SYSFS info for autologin/pNFS export
Introduce sysfs infrastructure for exofs cluster filesystem.
Each OSD target shows up as below in the sysfs hierarchy:
/sys/fs/exofs/<osdname>_<partition_id>/devX
Where <osdname>_<partition_id> is the unique identification
of a Superblock.
Where devX: 0 <= X < 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.
