AutoTopicCreationType partitioned not supported when passing through proxy

[KannarFr]

Describe the bug
When auto topic creation type is partitioned, the ServerCnx handles get PartitionMetadata by creatiing partitions in fetchPartitionedTopicMetadataCheckAllowAutoCreationAsync.

Proxy has other way to handle that and not support the partitioned topics auto creation because it directly answer the current ZK content and not creates partitions.

Expected behavior
Broker & Proxy should have the same way to handle auto topic creation.

@codelipenghui I finally get what what's wrong! Can you work on fixing it?
