Kafka Pump does not auto-reconnect when partition leader fails/changes

**Description:**

While testing iDRAC Telemetry in a multi-broker Kafka HA setup, we observed that the Kafka Pump does not automatically reconnect to a new leader when the current partition leader fails/changes even though the pump is configured with a headless service.

**Steps to Reproduce:**

- Configure Kafka with multiple brokers and replication factor = 3.
- Start the Kafka Pump and have it write to a specific partition (e.g., partition 0).
- Kill the leader broker for that partition.
- Observe that the Kafka Pump stops sending data.

**Expected Behavior:**
The Kafka Pump should detect the partition leader change and automatically reconnect to the new leader broker, resuming data ingestion without manual intervention.

**Actual Behavior:**
The Kafka Pump still tries to push data to the dead broker remains disconnected from the topic/partition until it is restarted or manually redirected.

**Impact:**

Breaks continuous telemetry ingestion in HA scenarios.
Requires manual intervention, reducing system reliability.
