Review Comment:
In retries document
https://kafka.apache.org/documentation/#producerconfigs_retries, it mentions
```
Enabling idempotence requires this config value to be greater than 0.
If conflicting configurations are set and idempotence is not explicitly
enabled, idempotence is disabled.
```
I think we should add assertion to `__int__` to make sure if
enable_idempotence is true, then retries should not be zero.
