Migrate to directory of pickled obj

[aterrel]

Convert all the shelve scripts over to the new dir of pickled objects.

trouble with database: when updating with pickled jobs, run into 'mem_LowTotal' is an invalid keyword argument for this function when running the following code (line 155 in the script I just pushed to my git)

job_dict = {
'system': system,
'acct_id': a_job.id,
'owner': owner,
'queue': a_job.acct['queue'],
'queue_wait_time': a_job.start_time - a_job.acct['submission_time'],
'begin': a_job.start_time,
'end': a_job.end_time,
#'nr_bad_hots': nr_bad_hosts,
'nr_slots': a_job.acct['slots'],
'pe': a_job.acct['granted_pe'],
'failed': a_job.acct['failed'],
'exit_status': a_job.acct['exit_status'],
}
job_dict.update(job.JobAggregator(a_job).stats)
#newJob.nr_hosts = len(a_job.hosts)
try:
newJob = tsm_Job(**job_dict)
newJob.save()
except DatabaseError,TypeError:
print "Error on job,", a_job.id
transaction.rollback()

(note, got this from your build_database.py).

Could it be an issue with what job objects I pickled and the stats in them? I just don't know where to start looking so some direction on this would be greatly appreciated!
