refactor job initiation routes in

[ghukill]

Most jobs have something similar, if not identical to the following, refactor. Consider having CombineJob from models.py handle request.POST directly.

                # get job name
        job_name = request.POST.get('job_name')
        if job_name == '':
            job_name = None

        # get job note
        job_note = request.POST.get('job_note')
        if job_note == '':
            job_note = None

        # retrieve jobs to merge
        input_jobs = [ models.Job.objects.get(pk=int(job)) for job in request.POST.getlist('input_job_id') ]        
        logger.debug('analyzing jobs: %s' % input_jobs)

        # get preferred metadata index mapper
        index_mapper = request.POST.get('index_mapper')

        # get requested validation scenarios
        validation_scenarios = request.POST.getlist('validation_scenario', [])

        # handle requested record_id transform
        rits = request.POST.get('rits')
