Description

Currently, the Mesos job cluster is not that easy to use. You have to manually serialize the job graph and specify the job graph file path. And the only way to include the user code jars is to put them in the `lib` folder. 

`StandaloneJobClusterEntrypoint` is a good example to learn. It can include the user code jars and allow to specify the entry class.  That way we would not need to generate the JobGraph yourself and then serialize it. I would like to enhance `MesosJobClusterEntrypoint` similarly.
