Adding Jq to ksql-cli image

[Guilamb]

As an User, I have a need to manipulate image tool's output such as ksql or ksql-test-runner.
For now, I've created a custom image : https://github.com/orange-cloudfoundry/orange-ksql-enriched
But I think it might be a great add to the base image.

I need :

Some tool like jq to process JSON outputs.

Suggested solution :

Include jq into ksql image.

Observed behavior :

As a user of ksql and ksql-test-runner tool in order to manipulate data. I use jq to read output of ksql queries, and also to organize my test data.

JSON being a supported by ksql, the image should have some tooling available to properly read data in this format.
