[improve][broker] Improve the log when namespace bundle is not available

[BewareMyPower]

Motivation

The Namespace bundle for topic (%s) not served by this instance log does not include the actual bundle info. We can check logs of OwnershipCache to see a bundle's ownership. But it's hard to see if the current topic's bundle is owned by the current broker when the error happens. We have to manually compute the hash code and see which bundle this topic belong to.

long hashCode = Hashing.crc32().hashString(topicName.toString(), StandardCharsets.UTF_8).padToLong();
System.out.println(String.format("0x%x", hashCode));

Modifications

Return the bundle info in checkTopicOwnership as well.
