Command-line utility

[bschroeter]

I've come across a use case where it would be useful to be able to use HPCpy to batch-submit multiple PBS jobs without writing any python code.

Consider the following command:

hpcpy submit job_script.sh args.yml

Where job_script.sh is the job script template and args.yml provides the parameters that are interpolated into the job script and details about the submission (directives etc.) and how it is batched (i.e. providing a syntax for looping through and submitting jobs)

To achieve this currently a python script is required to define all of the details surrounding submission of a job script template, with this approach it is possible to omit the former.

This will also open up the possibility of utility functions such as hpcpy clean which can clear the rendered job scripts from the user home directory immediately, without having to wait for the next hpcpy submission to age them out.

Big piece of work, target v2.0.0
