Description of problem
======================
Previously when a read is requested, AFR was returning only one uuid out of the
two replica bricks, but this meant that when a rebalance was triggered only one
brick participating and hence load balancing was missing.
This problem was fixed with BZ#1315781 - AFR returns the node uuid of the same
node for every file in the replica

However this fix didn't consider other scenarios and consumers of this
facility.
for eg, georep too was relying on this service from AFR, and now with this
service, it means that georep will be served by both replica bricks and hence
syncing of data can happen twice for the same data. Now instead of one brick
being passive and other being active, both turn active and hence lead to
unnecessary resource utilization(eg CPU)
