Update topic expiry time in Metadata every time the topic metadata is
requested
As of current implementation, KafkaProducer.waitOnMetadata() will first
reset topic expiry time of the topic before repeatedly sending
TopicMetadataRequest and waiting for metadata response. However, if the
metadata of the topic is not available within Metadata.TOPIC_EXPIRY_MS, which
is set to 5 minutes, then the topic will be expired and removed from
Metadata.topics. The TopicMetadataRequest will no longer include the topic and
the KafkaProducer will never receive the metadata of this topic. It will enter
an infinite loop of sending TopicMetadataRequest and waiting for metadata
response.
This problem can be fixed by updating topic expiry time every time the
topic metadata is requested.
