Say there are multiple kafka brokers running, if a broker goes down, instead of refreshing the metadata immediately the sarama library uses the cached cluster metadata for it.

And also during leader election, there's similar problems

Describe the solution you'd like
Similar problems are seen in issues like:
IBM/sarama#2173
IBM/sarama#2237
IBM/sarama#272
There could be other ways to solve this problem like, but I propose exposing sarama config to let the user configure the RefreshFrequency https://github.com/IBM/sarama/blob/main/config.go#L151
