Added transport action for bulk async shard fetch for primary shards

[sudarshan-baliga]

Description

This PR for adding the transport action for the async fetching of the shard information for bulk of shards from the nodes in a single request per node. Code is inspired by the existing transport action TransportNodesListGatewayStartedShards.java which fetches just one shard information from the node per request.

• Added transport action TransportNodesBulkListGatewayStartedShards.java for fetching the shards data on a node in bulk.
• POC code where testing was done https://github.com/opensearch-project/OpenSearch/pull/7269/files#diff-c1a7825492dba9f1ba34affffcead20eab136eb67283f89d81295fcef2a8a3ff

The backport to 2.x failed:

The process '/usr/bin/git' failed with exit code 128

To backport manually, run these commands in your terminal:

# Navigate to the root of your repository
cd $(git rev-parse --show-toplevel)
# Fetch latest updates from GitHub
git fetch
# Create a new working tree
git worktree add ../.worktrees/OpenSearch/backport-2.x 2.x
# Navigate to the new working tree
pushd ../.worktrees/OpenSearch/backport-2.x
# Create a new branch
git switch --create backport/backport-8218-to-2.x
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 8cb4bb4c1776aaee3c4065c5a6b43e86a1e52daa
# Push it to GitHub
git push --set-upstream origin backport/backport-8218-to-2.x
# Go back to the original working tree
popd
# Delete the working tree
git worktree remove ../.worktrees/OpenSearch/backport-2.x

Then, create a pull request where the base branch is 2.x and the compare/head branch is backport/backport-8218-to-2.x.
