Update kafka_log_log_size in jmx exporter config to duplicate partition and topic labels

WHAT

Update Kafka JMX exporter config (in fleetshard), to duplicate topic label to topic_name, and partition label to partition_id (keep the existing label names, since those are still used...a follow up task will remove usage of them, and then maybe a follow-follow-up to remove this duplication.

WHY

Those are the label names decided upon by the consistent user-facing metrics naming, and we're adding this new user-facing metric, and even though that consistency hasn't been rolled out anywhere else, it was decided to do it for this metric because it's new.

HOW

<Suggestions for how this may be solved.> [Optional]

DONE

Include the following where applicable:

• <bulleted list of functional acceptance criteria that need to be completed>
• <call out anything on the documentation side that's needed as a result of this task being completed>
• <any metrics, monitoring dashboards and alerts that need to be created or be updated>
• <SOP creation or updates>

Guidelines

The following steps should be adhered to:

• Required tests should be put in place - unit, integration, manual test cases (if necessary)
• CI and all relevant tests passing
• Changes have been verified by one additional reviewer against:
• each required environment
• each supported upgrade path
• If the changes could have an impact on the clients (either UI or CLI), a JIRA should be created for making the required changes on the client side and acknowledged by one of the client side team members. PR has been merged
