Changes look good in perspective of fixing the bug @rajiv-kv. Can we have a follow up issue where we can look into the optimization where if there multiple replicas of a shard, we don't need n round of reroutes/fetches to get them assigned? It would be good to see that optimization in future.

Description
ShardsBatchGatewayAllocator de-dupes the unassigned Shards based on ShardRouting. If index is configured with muliple replicas, there will be multiple ShardRouting entries for same replica shard. The equals comparison of ShardRouting includes comparison based on <ShardMetada, UnassignedInfo>. This can cause incorrect de-duplication if UnassignedInfo is different for Replica copies. Hence changing the implementation to de-dupe based on ShardId, so that only one entry is created in cache and there are no duplicate entries across batches.
