When starting a KafkaConsumer, we need to call the position API to establish the next offset BEFORE reading the partition from raw redis.
This ensures that we will not miss any UVE changes that happen between the partition read and when we starting reading from kafka.

Moved mockkafka to broker version 0.9.0.1, to be compatible with the fallback kafka version used collector via librdkafka

set offsets.topic.replication.factor to 1 for kafka-broker to in mockkafka to prevent spurious errors in systemless test

Re-enabled the redis restart systemless test
