provide operator-managed properties to configure Loki 'limit' settings e.g.: as described here=> https://grafana.com/docs/loki/latest/configuration/#limits_config

• as a specific example: the split_queries_by_interval limit

*Use case description*Lokistack performance and serviceability are heavily impacted by the setting of limits to manage query execution and other consideration. The default settings for these limits are often not adequate for operational use: not being able to change these limits severely limits the usability of Loki for log aggregation queries.

For example: changing the split_queries_by_interval and max_query_parallelism can change a query that fails outright due to timeouts into a perfectly usable and performant request.
