Fix default_validity cache setting typo

CHANGELOG.md

@@ -8,6 +8,7 @@
   * `--store.min-chunk-age` has been removed
   * `--querier.query-store-after` has been added in it's place.
 * [CHANGE] Experimental Memberlist KV store can now be used in single-binary Cortex. Attempts to use it previously would fail with panic. This change also breaks existing binary protocol used to exchange gossip messages, so this version will not be able to understand gossiped Ring when used in combination with the previous version of Cortex. Easiest way to upgrade is to shutdown old Cortex installation, and restart it with new version. Incremental rollout works too, but with reduced functionality until all components run the same version. #2016
+* [CHANGE] Renamed the cache configuration setting `defaul_validity` to `default_validity`. #2140
 * [FEATURE] Added user sub rings to distribute users to a subset of ingesters. #1947
   * `--experimental.distributor.user-subring-size`
 * [FEATURE] Added flag `-experimental.ruler.enable-api` to enable the ruler api which implements the Prometheus API `/api/v1/rules` and `/api/v1/alerts` endpoints under the configured `-http.prefix`. #1999
