Update sacct call with AllocTRES

[Bubballoo3]

#958 adds the alloc-tres flag to squeue, and it made me wonder if we should update the sacct call in info_historic as well. On the surface, it seems like this is able to fetch the memory allocation for completed jobs that squeue would be unable to, though this isn't used in ondemand so not sure how much of a priority this would be

Oh I see why you're mentioning sacct now. Yea we should do this. I don't think historic_info isn't used but will be some day, we're always getting asked about it being here or there.
