Add status to Job objects

[Diego]

It would make sense to have available the status of a Job object since it is something which is run and it is expected to be completed at some point in time.

Solution, access directly to the json obj

>>> wq = pykube.Job.objects(api).filter(namespace=pykube.all).watch()
>>> for job in wq:                                                   
...     print(job[1].obj.get('status'))
