afr: Automagic unsplit-brain by [ctime|mtime|size|majority]
Introduce cluster.favorite-child-policy which when enabled with [ctime|mtime|size|majority], automatically heals files that are in split-brian. The majority policy will not pick a source if there is no majority. The other three policies pick the first brick with a valid reply and non-zero ctime/mtime/size as source.
