Review comment:
Understood. It seems
[`MetadataStore`](https://github.com/apache/pulsar/blob/master/pulsar-metadata/src/main/java/org/apache/pulsar/metadata/api/MetadataStore.java#L53)
APIs are following a different pattern: all IO operations are asynchronous by
default. So I think `MetadataStoreLifecycle#initializeCluster` should be
designed in the same way.
