CLI-3550: Confluent kafka link create is not providing feedback from config.txt that the tasks are in error and has no documentation on what is expected in the config.txt file.

[kcarter-bread]

Confluent CLI is lacking documentation on how to pass through arguments for syncing consumer offsets, ACL's and auto creating mirror topics.

confluent kafka link create $LINK_NAME \

--cluster $DEST_CLUSTER_ID \

--source-cluster $SOURCE_CLUSTER_ID \

--source-bootstrap-server $BOOTSTRAP_ENDPOINT \

--source-api-key $API_KEY \

--source-api-secret $API_SECRET \

--destination-cluster $DEST_CLUSTER_ID \

--config config.txt

# config.txt: 
auto.create.mirror.topics.enable=true
consumer.offset.sync.enable=true
acl.sync.enable=true

This creates the cluster link and reports no errors in the cli but when checking the tasks on the link they're reporting status in_error:

confluent kafka link task list --link [link-name]

  TopicConfigsSync   | ACTIVE   |

There are no hints in the cli for what is expected here, there is no documentation that I can find to get consumer offsets ACL's to sync or auto-create mirror topics via the cli

If I hadn't caught this before my DR failover, consumers wouldn't know where to begin with processing.

this is on confluent version v4.21.0

to temporarily resolve this I was able to create the link in the UI.
