* refactor grafana_index_server_index_size to calculate in a goroutine instead of at scrape time and remove grafana_index_server_indexed_docs metric * use wire to inject bleve index metrics * remove sprinkles metrics from bleve index metrics * log error when trying to calculate file index size and bump interval to 1m instead of 5s
