Update for Pulsar 2.9

[EronWright]

Please update the codebase for Pulsar 2.9. I observe there are dependencies on PulsarService::getLocalZkCache (which was removed in 2.9).

The topic lookup aspect seems in need of improvement. Be aware that most ZK structures use the broker's canonical name as the key, which is based on that broker's advertisedAddress:webServicePort. This is not the same as the broker service URL that is returned from the LookupService. The lookup service returns information from advertisedListeners which isn't necessarily the same value.

Thanks for your suggestion.

The method PulsarService::getLocalZkCache was called in method AmqpCommandDecoder::getProtocolDataToAdvertise, it seems that this method isn't used, I'll remove it.
