A "registration" represents an identifier for a set of consumer(s) interested in subscription(s). When we say a "registration" here, we mean "an object of type DatabusV3Registration" The user of the client library can specify a "RegistrationId" for the registration. If that RegistrationId is currently not in use, it is allotted for the returned DatabusV3Registration object. If the user does not specify the RegistrationId, the library currently assigns one. The registration gets the same id upon a restart. The persisted checkpoint for this particular consumerGroup is identified through the RegistrationId, which is a hash generated off the consumer subscriptions. {@link DatabusV3Client#registerDatabusListener(DatabusV3Consumer,RegistrationId,DbusKeyCompositeFilterConfig,DatabusSubscription)}/ {@link DatabusV3Client#registerCluster(String,DbusClusterConsumerFactory,String)}DatabusClient interface methods implemented by DatabusHttpV3ClientImpl
