      Description

      Currently, a Statestore subscriber starts a separate thread after the initial registration with Statestore to periodically check if the Statestore may have failed and re-registered with Statestore if necessary. Similarly, the function StatestoreSubscriber::Register() also relies on the old Thrift client's retry logic to retry failed RPC attempts to Statestore. This is needed as the initial registration relies on this retry logic to wait for Statestore to startup in case an Impala daemon starts before the Statestore. These two retry paths may be consolidated.
