Fix TLS stability issues with V2 protocol that caused data corruption

- add the TLS handler after the FlushConsolidationHandler
  - This makes TLS connections from Pulsar Broker to Bookkeeper stable
    when bookkeeperUseV2WireProtocol=true is used
- Fix test TestTLS for V2
- Fix inconsistency in client configuration in BookKeeperClusterTestCase
