Do we need to invalidate the cache if the event is SessionReestablished?

I added this event, and I noticed that as long as the event SessionReestablished occurs, the event Reconnected must occur, this causes the cache will be cleaned twice, but this should have no other bad effects. See:

…21035) Motivation: After [PIP-118: reconnect broker when ZooKeeper session expires](#13341), the Broker will not shut down after losing the connection of the local metadata store in the default configuration. However, before the ZK client is reconnected, the events of BK online and offline are lost, resulting in incorrect BK info in the memory. You can reproduce the issue by the test `BkEnsemblesChaosTest. testBookieInfoIsCorrectEvenIfLostNotificationDueToZKClientReconnect`(90% probability of reproduce of the issue, run it again if the issue does not occur) Modifications: Refresh BK info in memory after the ZK client is reconnected. (cherry picked from commit db20035)
