[Enhancement] Update TransportIndicesShardStoresAction to fetch the shard metadata using batch call

[amkhar]

Describe the bug
Original Issue opened : #5098 . This issue is a sub task for the overall project defined #8098.

Description
Today, during node drop and joins, we fetch the metadata of unassigned shards on per shard basis. As part of #8098 revamp project, we are changing the fetch from per shard to a batch of shards.

TransportIndicesShardStoresAction is another action which fetches the metadata of shards in async manner, currently it loops over the given shard and call fetch data. We need to use newly created transport TransportNodesListGatewayStartedShardsBatch to move this flow on new transport actions.

Additional context
Please go through the discussion #5098 to understand the overall enhancement approach and check #8098 to see the sub tasks of overall project.
