[Snapshot V2] Add support for remote store files cleanup #15466
Description
Is your feature request related to a problem? Please describe
As part of shallow snapshot delete flow, we need to handle deletion of remote store files for deleted indices.
Describe the solution you'd like
There is a logic in place to handle deletion of remote store files for indices that have been deleted but are part of the snapshot. The existing logic looks at snapshot shard metadata file to figure out the remote store path strategy and algorithm for deletion. Since snapshot v2 is not writing per shard snapshot metadata file in the snapshot repo, it needs to get the path from index metadata.
