> As part of KAFKA-14021, we made a change to MirrorConnectorConfig.sourceConsumerConfig() to grab all configs that start with "source.". Previously it was grabbing configs prefixed with "source.cluster.". 
> This means existing connector configuration stop working, as configurations such as bootstrap.servers are not passed to source consumers.
> For example, the following connector configuration was valid in 3.4 and now makes the connector tasks fail:
> {code:json}
> {
>     "connector.class": "org.apache.kafka.connect.mirror.MirrorSourceConnector",
>     "name": "source",
>     "topics": "test",
>     "tasks.max": "30",
>     "source.cluster.alias": "one",
>     "target.cluster.alias": "two",
>     "source.cluster.bootstrap.servers": "localhost:9092",
>    "target.cluster.bootstrap.servers": "localhost:29092"
> }
> {code}
> The connector attempts to start source consumers with bootstrap.servers = [] and the task crash with 
> {noformat}
