### Description of PR Current implementation for router state store update is quite inefficient, so much that when routers are removed and a lot of NameNodeMembership records are deleted in a short burst, the deletions triggered a router safemode in our cluster and caused a lot of troubles. This ticket contains 2 parts: improving the deletion process for ZK state store implementation, and allowing the overwrite part and delete part of org.apache.hadoop.hdfs.server.federation.store.CachedRecordStore#overrideExpiredRecords to run in parallel. ### How was this patch tested?
