Review comment:
I see the symmetry with `connectorInfo` above. But here we return a map,
in which case it might be safer and nicer to return an empty map? Wdyt?
In terms of response the result will be the same because if the connector is
found it will always have a map of maps.

Review comment:
I agree with your choice to preserve symmetry. Yet some features need to
find their way to the codebase eventually. There's a PR in progress to apply
some basic modernization and reduce boilerplate. Want to use a lambda and skip
the need to synchronize merges with: https://github.com/apache/kafka/pull/9867 ?

If you change above, don't forget to check with empty here.

Should we add one more test to test multiple tasks with multiple config
properties?
