As the moment the IQ is only thrown InvalidStateStoreException for all errors. That means the user cannot handle different types of errors. We should throw different exceptions for different types.
Add two new exception class for the IQ state store errors:
public class StateStoreMigratedException extends InvalidStateStoreException
public class StateStoreClosedException extends InvalidStateStoreException
StateStoreMigratedException used for state store not available and may have been migrated to another instance, the user needs re-discovering its location.
StateStoreClosedException used for state store is closed.(RocksDBStore, WrappedStateStore)
No
