"Loki / Chunks" dashboard uses undefined metrics

[rfratto]

The "Loki / Chunks" dashboard in the Loki mixin here references the following metrics that are not defined in Loki:

• loki_ingester_memory_chunks
• loki_ingester_memory_series
• loki_ingester_chunk_utilization
• loki_ingester_chunk_length
• loki_chunk_store_index_entries_per_chunk
• loki_ingester_flush_queue_length

It is not clear to me if these metrics need to be defined or if the mixin needs to be updated to use the appropriate currently existing metrics.
