Clean up deprecated features for 2.14

CHANGELOG.md

@@ -32,6 +32,8 @@
 * [CHANGE] Querier: allow wrapping errors with context errors only when the former actually correspond to `context.Canceled` and `context.DeadlineExceeded`. #9175
 * [CHANGE] Query-scheduler: Remove the experimental `-query-scheduler.use-multi-algorithm-query-queue` flag. The new multi-algorithm tree queue is always used for the scheduler. #9210
 * [CHANGE] Distributor: reject incoming requests until the distributor service has started. #9317
+* [CHANGE] Ingester, Distributor: Remove deprecated `-ingester.limit-inflight-requests-using-grpc-method-limiter` and `-distributor.limit-inflight-requests-using-grpc-method-limiter`. The feature was deprecated and enabled by default in Mimir 2.12. #9407
+* [CHANGE] Querier: Remove deprecated `-querier.max-query-into-future`. The feature was deprecated in Mimir 2.12. #9407
 * [FEATURE] Alertmanager: Added `-alertmanager.log-parsing-label-matchers` to control logging when parsing label matchers. This flag is intended to be used with `-alertmanager.utf8-strict-mode-enabled` to validate UTF-8 strict mode is working as intended. The default value is `false`. #9173
 * [FEATURE] Alertmanager: Added `-alertmanager.utf8-migration-logging-enabled` to enable logging of tenant configurations that are incompatible with UTF-8 strict mode. The default value is `false`. #9174
 * [FEATURE] Querier: add experimental streaming PromQL engine, enabled with `-querier.query-engine=mimir`. #8422 #8430 #8454 #8455 #8360 #8490 #8508 #8577 #8660 #8671 #8677 #8747 #8850 #8872 #8838 #8911 #8909 #8923 #8924 #8925 #8932 #8933 #8934 #8962 #8986 #8993 #8995 #9008 #9017 #9018 #9019 #9120 #9121 #9136 #9139 #9140 #9145 #9191 #9192 #9194 #9196 #9201 #9212 #9225 #9260 #9272 #9277 #9278 #9280 #9281 #9342 #9343 #9367 #9368 #9371
