It would be good to have a way to emit Pulsar source and sink configuration properties to logs.

Currently, logs from behaviour need to be checked to see if a property is set.
For example, if failonwrite is set to true, and there is a sink write failure, then we would be getting a "callback error" message in the log.
However this would appear only if there was an actual failure, and we cannot know whether the property is set otherwise from logs.
