LP#1895052: Allow pickup lib to control stalling

This commit provides a new YAOUS that, when set, takes precedence over
the current "soft stalling interval" YAOUS.  Instead of limiting capture
to items owned by the pickup library (or the directly targeted item)
based on the context of scanned item's circulating library, it instead
restricts op capture to holds that have a pickup library of the scanning
location when the hold is younger that the interval, base on the context
of the pickup location of each hold.

tl;dr: It allows the pickup library to control op capture stalling
rather than the circulating library of an arbitrary scanned item.
