This PR exposes metrics from TSDB's compactor "syncer" component. In Cortex, we instantiate multiple syncers, new one for each sync operation. Because of this, approach used to gather metrics is different from previous TSDB metrics work.
Here we register fixed set of metrics that are exported, and we update them when syncer has done its job, via
defer c.syncerMetrics.gatherThanosSyncerMetrics(reg)incompactUsermethod.Since tsdb.Compactor is reused between
compactUsercalls, we don't need to handle those metrics (they are expored with their originalprometheus_tsdb_compactionsprefix)Checklist
