Review Comment:
In Go SDK, the partition index less than 0 is not allowed.
```
// did we receive a valid partition index?
if partition < 0 || partition >= len(c.consumers) {
c.log.Warnf("invalid partition index %d expected a partition
between [0-%d]",
partition, len(c.consumers))
return trackingMessageID{}, false
}
```
And why do we need to modify the current logic, where the number of
consumers is equivalent to the number of partitions, and each partition
corresponds to a unique consumer.
The Go SDK currently does not support seek operations on partitioned topics,
and this logic is still being implemented.
