Also, the new brick should not be considered as source for healing till it is up to date. Previously, extended attributes had to be set manually on the bricks for this to happen. This patch is part 1 patch to automate this process.

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.
