Review Comment:
> When we get API versions from any node
The optimal way of handling this is to have an ApiVersionsRequest callback
and check the transaction version in it. However, it is a bit tricky here. The
ApiVersionsRequest is handled in the KafkaClient, a layer below the Sender
class. It does not expose any interaction method other than the _apiVersions_
object. If we want to register a callback, we should have an interface change
in the KafkaClient which may need a KIP?
A suboptimal way is to check the _apiVersions_ for all the node features
when calling the _coordinatorSupportsTransactionV2_. I guess it is acceptable
as the checking does not cost much.
