Deprecated performance metrics

Command response time metrics in all monitoring groups are deprecated. These metrics have names ending in avg_rt, such as del_avg_rt and exists_avg_rt in the Keys group. The deprecated metrics include: del_avg_rt, dump_avg_rt, exists_avg_rt, expire_avg_rt, expireat_avg_rt, move_avg_rt, persist_avg_rt, pexpire_avg_rt, pexpireat_avg_rt, pttl_avg_rt, randomkey_avg_rt, rename_avg_rt, renamex_avg_rt, restore_avg_rt, sort_avg_rt, ttl_avg_rt, type_avg_rt, and scan_avg_rt.

All monitoring groups for proxy nodes except for the Basic Monitoring Group are deprecated. Proxy nodes will now support only the Basic Monitoring Group. In the Custom Metrics dialog box, the selectable monitoring groups include the basic monitoring group, Keys group, String group, Hashes group, Lists group, Sets group, Zset group, HyperLog group, Pub/Sub group, and Transaction group. The Sets group and Transaction group also contain deprecated metrics ending with avg_rt.
