Too many parallel open-ils.actor.user.itemsout.notices requests

[Jeff Davis]

EG 3.5

Another follow-up to bug 1896285. The Items Out tab appears to fire off a separate open-ils.actor.user.itemsout.notices call for each row in the grid. If you have enough rows, this can exhaust open-ils.actor drones pretty quickly.

Thanks, Bill! With the fix in place, loading the Items Out grid no longer causes a spike in open-ils.actor drones. However, for accounts with lots of checkouts, it takes a lot longer to populate the grid -- over 10 seconds for a patron with 100 circs in my test environment. (Without the fix, it starts to populate almost immediately.)

Here's a working branch with a signoff for Bill's commit, plus a second commit adding a progress dialog for the Items Out grid:

Alternatively we could look for a way to load the grid faster while still avoiding excessive API calls.

Working for me in PINES production. Pushed to master, rel_3_6, and rel_3_5. Thanks, Bill and Jeff!
