Thanks [~tomasflobbe], that is a good idea.
I attached a patch for this ticket. Whenever a request gets failed we will
check the {{IndexWriter.tragedy}} if there is another active replica in the
same shard and the current replica is the leader (no need for handle the case
when the replica is not leader since the leader will bring the replica into
recovery state). It will enqueue a DELETE and ADD operation to the Overseer.

Just a thought here, but what about anything inside {{IndexWriter.tragedy}}?
