title: Airflow, Is there a way to provide metadata about a task that can be displayed on the console
body: <p>I am using airflow to run a pipleine. Each task takes a Jar from a defined location and runs it. This location only contains the jar and so is inconvenient for any support tasks where a user needs to find the jar source code. Is it possible to display a link to the Jars source code repo somewhere on the airflow console. I know I could just include an echo command in the BashOperator but this seems a bit messy. Is there anyway to include the link in the task instance details for example?</p>
