Chore: Upgrade weaveworks/common

CHANGELOG.md

@@ -37,6 +37,8 @@
 * [ENHANCEMENT] Memberlist: expose configuration of memberlist packet compression via `-memberlist.compression=enabled`. #4346
 * [ENHANCEMENT] Update Go version to 1.16.6. #4362
 * [ENHANCEMENT] Updated Prometheus to include changes from prometheus/prometheus#9083. Now whenever `/labels` API calls include matchers, blocks store is queried for `LabelNames` with matchers instead of `Series` calls which was inefficient. #4380
+* [ENHANCEMENT] Exemplars are now emitted for all gRPC calls and many operations tracked by histograms. #4462
+* [ENHANCEMENT] New options `-server.http-listen-network` and `-server.grpc-listen-network` allow binding as 'tcp4' or 'tcp6'. #4462
 * [BUGFIX] Compactor: compactor will no longer try to compact blocks that are already marked for deletion. Previously compactor would consider blocks marked for deletion within `-compactor.deletion-delay / 2` period as eligible for compaction. #4328
 * [BUGFIX] HA Tracker: when cleaning up obsolete elected replicas from KV store, tracker didn't update number of cluster per user correctly. #4336
 * [BUGFIX] Ruler: fixed counting of PromQL evaluation errors as user-errors when updating `cortex_ruler_queries_failed_total`. #4335
