Backport of #71674

…lastic#71674)

This change adds a test module called `error-query` that exposes a
query builder to simulate errors and warnings on shard search request.
The query accepts a list of indices and shard ids where errors or warnings
should be reported:
```
POST test*/_search
{
    "query": {
        "error_query": {
            "indices": [
                {
                    "name": "test_exception",
                    "shard_ids": [1],
                    "error_type": "exception",
                    "message": "boom"
                },
                {
                    "name": "test_warn*",
                    "error_type": "warning",
                    "message": "Watch out!"
                }
            ]
        }
    }
}
```

The `error_type` can be set to `exception` or `warning` and the `name` accepts
simple patterns, aliases and fully qualified index name if the search targets remote shards.

This module is published only within snapshots like the other test modules.
