feat: Update bindings to 2.12.1

Mainly want to see an update to to the reconnection issue on 2.10. Changes the test kafka to bitnamilegacy/kafka as all images were moved
here. Seems to be a risk that these images will also be removed at some point so finding another source for running kafka for testing would be good.

Closes fede1024#789
