Not directly related to this PR: Why is this variable called `currentTimeMs`?

Review Comment:
This does not seem to be true. The constructor is not called in tests and
also the constructors that call this constructor are not called in tests. That
is one reason I do not like this kind of comments, because they easily start to
lie.

Review Comment:
I guess it does not make a big difference if the timer is set when the
unsent request is created vs. when the unsent request is added to the network
client, right?

Review Comment:
Why do we only check expiration in case of a `TimeoutException` but not for
other retriable exceptions?
The `TopicMetadataRequestManager` handles this differently.

Review Comment:
Not directly related to this PR: is it OK to use the rebalance timeout here
instead of using a timer that computes the remaining time until the rebalance
timeout is expired?
