Major Description
It would be nice to be able to use the docker container to generate a fat jar or a project metadata export.
This way you can do both things without the need to download and unzip the Hop client.
For example if you're working on a Spark or Flink master and want to execute a pipeline you could just create a fat jar simply using docker.
Suggested variable names: HOP_FAT_JAR and HOP_METADATA_EXPORT
