Description of problem:
On increasing the replica count of a replicate volume (by add-brick command),
self-heal upon failure of a fop on old-brick and success on newly added brick
could lead to reverse heal and hence data loss.

Pending xattrs should be marked indicating the new brick doesn't have the
latest copy of data yet.
