mdadm: add man page for --add-journal
Add the following to man page:
--add-journal
Recreate journal for RAID-4/5/6 array that lost a journal device.
In the current implementation, this command cannot add a journal
to an array that had a failed journal. To avoid interrupting
on-going write opertion --add-journal only works for array in
Read-Only state.
