WHAT
Add support to set the `suspended` property for a Kafka instance to kafka-storage-expansions.
https://gitlab.cee.redhat.com/mk-ci-cd/kafka-storage-expansions

WHY
Allow a Kafka instance to be manually suspended and resumed from suspension using the same or similar process that is used to expand storage.

HOW

• Add suspension_overrides field to the configuration used by the tool and add a functionality to the script for processing this new field to suspend/pause a kafka instance.

• Rename the tool to something more generic and clear for its wider scope.

DONE

• Tool and configuration refactored to allow for instances to suspended / unsuspended according to matching criteria specified in the configuration yaml.
• Tool is renamed from kafka-storage-expansions.
