Batch or serialize requests on Edit Due Date in Items Out tab

[Jeff Davis]

EG 3.7

1. Check out a large number of items to a patron.
2. Retrieve the patron and go to the Items Out tab.
3. Select all items and do Actions > Edit Due Date.

The client will make a separate open-ils.circ.circulation.due_date.update call for each item, which results in drone exhaustion if the number of items exceeds the max_children setting for open-ils.circ (you should see "no children available" warnings in the logs).

We saw this happen today.

Working branch user/jeffdavis/lp1932203-serialize-items-out-edit-due-date addresses the issue by serializing API calls:

I drove this one around the block a couple of times, and it works for me on 3.7.3, 3.9.0, and latest master.

I've pushed the patch to master, rel_3_9, rel_3_8, and rel_3_7. I figure this is a performance patch that is close enough to a security patch to warrant being in a 3.7.4 relase.

Thanks, Jeff!
