feat: support upgrading kafka broker metadata.version with cp-ansible

[oc]

Description

Support for bumping metadata.version using cp-ansible when running Kraft mode.

Play activated when new variable: kafka_broker_metadata_version is specified and cluster running in kraft_mode.

kafka_broker_metadata_version should hold the desired metadata.version. It should in most cases track the major.minor of the underlying Apache Kafka version, like: 3.7, 3.8, etc

See for instance: https://kafka.apache.org/documentation/#upgrade_380_kraft
