Insufficient Elasticsearch permissions for default index names

[willbrownecs]

🐛 Summary

The recommended Elasticsearch role provides insufficient index permissions for the default index names used by the search streamer.

To reproduce

Steps to reproduce the behavior:

1. Follow documentation for creating Thorium role
2. Deploy a new ThoriumCluster
3. Observe that the search-streamer pod Crash-loops due to insufficient permissions for creating the default indices

Updating the Role to:

{
  "indices": [
    {
      "names": ["thorium*", "results"],
      "privileges": ["all"]
    }
  ]
}

resolves the issue.

Expected behavior

Search streamer pod creates successfully and has sufficient permissions to create default indices.
