I verified that this removed the dependency by doing this:
```
./gradlew install -x check -x test
find | grep jackson | grep jar$ | xargs -l rm
```
And then testing the console consumer and console producer continued to work.
(Since the broker does require jackson to run I was using a prebuilt kafka
to run the clients against).
Without this PR, the console consumer fails with this exception when the
Jackson jars are not present:
```
[2020-08-19 11:27:53,468] ERROR Error processing message, terminating
consumer process: (kafka.tools.ConsoleConsumer$)
java.lang.NoClassDefFoundError: com/fasterxml/jackson/databind/JsonNode
