Fixes the recovery not respect to the isolation group settings (apach…
…e#8961) --- *Motivation* When users configure to use ZkIsolatedBookieEnsemblePlacementPolicy, it is hard to configure AutoRecovery to respect to the isolation group settings. Because we don't store the isolation group information as part of ledger metadata, the framework doesn't have any information to use for choosing the bookies. *Modifications* - Change the ZkIsolatedBookieEnsemblePlacementPolicy to use the policy passed from the custom metadata
