    afr : Enable auto heal when replica count increases

                Backport of: http://review.gluster.org/12454

        This patch is part two change to prevent data loss
        in a replicate volume on doing a add-brick operation.

        Problem: After doing add-brick, there is a chance that
        self heal might happen from the newly added brick rather
        than the source brick, leading to data loss.

        Solution: Mark pending changelogs on afr children for
        the new afr-child so that heal is performed in the
        correct direction.
