To whom is this feature relevant?
-Resource owners

Please provide a one line description of the feature:
-Pure Python resources

How would the new feature work (appear in use)?
The existing Python option in the SCRIPTLANGUAGE of res conf should actually be fully supported.

How would the new feature be implemented?
We need frontend_script and *_node_script equivalents in python and genjobscriptpython.py should be updated to match genjobscriptsh functionality.

Please provide any additional information below.
We should use this task to get rid of the complete sequentiality of the resource handler actions as seen in the bash frontend and node scripts.
Using the new python multiprocess module may be a good idea. Also be careful to keep the option of having multiple backfill jobs as long as local resources remain free (i.e. two concurrent single CPU jobs on a dual core CPU).
