WHAT

Create a filter for non-storage billing metrics for Kafka instances where the bf2.org/suspended=true label has been set. Those metrics are:

• Cluster hours: kafka_id:strimzi_resource_state:max_over_time1h
• Traffic: kafka_id:haproxy_server_bytes_in_out_total:rate1h_gibibytes

WHY

Only storage usage should be considered for billing purposes when a Kafka instance has been suspended.

HOW

• Figure out a way on how to exclude suspended Kafka instances from billing metrics.
• These metrics are consumed by SubscriptionWatch directly from Observatorium (it does not go through KAS Fleet Manager).
• The billing metrics are defined in the observability-resources-mk repository

DONE

• Create new tasks once investigation is complete that will track how to implement this.
