THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!

We propose adding the new metric "connector-task-count" on the existing group name "connector-metrics" in the ConnectMetricsRegistry.
| MBean | Metric/Attribute Name | Description |
|---|---|---|
kafka.connect:type=connector-metrics,connector=([-.\w]+) | connector-task-count | The number of tasks of the connector. |
Proposed Changes
A new Connector level metric will be added, "connector-task-count". This metric will be calculated from the `Herder::connectorInfo` connectorStatus` method. In order to enable this change, the `WorkerConnector` will be constructed with a `Herder` to have access to the task statuses.
Metrics gathering should perform efficiently and be cheap to calculate. The newly proposed metric will call "AbstractHerder::connectorStatus", which synchronously returns the values from the KafkaStatusBackingStore's cache. The most expensive part of the function is sorting the taskStates.
Compatibility, Deprecation, and Migration Plan
