Improvement: Increase logging V-level in Apache Kafka scaler

[dkv]

Description:

The Apache Kafka scaler logs stuff at V(1) level in all cases but one, that uses V(0).
V(0) makes it impossible to suppress those logs, and in our case it's a lot of logging.

Proposal:

Log everything in the Apache Kafka scaler with at least V(1)

Tiny change. Change 0 -> 1 in: https://github.com/kedacore/keda/blob/main/pkg/scalers/kafka_scaler.go#L423
