jobtronaut cli batch submit

[rkoschmitzky]

Goal

Make it possible to batch submit multiple jobs in the jobtronaut commandline interface.

Motivation

The current jobtronaut cli is missing the option that we have in the API to submit multiple jobs at once. Although it is possible via a shell script to create a simple batch submission, merging multiple jobs sharing the same root task with different arguments sets can only be done via python yet.
Especially in combination with the --expandchunk flag a new option for handling this would be very powerful and make porting new subhierchies to jobtronaut even more attractive.

Difficulties

In Python we can express the task/job dependencies via a list vs. tuple syntax. How can we do this in the cli though?
