cluster/afr: Give option to do consistent-io
Problem:
When tiering/rebalance does migrations and afr with 2-way replica is in
picture, migration can read stale data if the source brick goes down and writes
to the destination. After this deletion of the file leads to permanent loss of
data after migration.
Fix:
Rebalance/tiering should migrate only when the data is definitely not stale. So
introduce an option in afr called consistent-io which will be enabled in
migration daemons.
