LP#1981714: add settings to control owning library of auto-added LIDs

Previously, when line item copies/details/items where automatically created
because the provider's default copy count is non-zero, the owning library
of those line item copies was set to the workstation library. This patch
adds two new settings to tweak this behavior:

* How to set default owning library for auto-created line item items

Stategy to use to set default owning library to set when line item items
are auto-created because the provider's default copy count has been set.
Valid values are "workstation" to use the workstation library, "blank"
to leave it blank, and "use_setting" to use the "Default owning library
for auto-created line item items" setting. If not set, the workstation
library will be used.

* Default owning library for auto-created line item items

The default owning library to set when line item items are auto-created
because the provider's default copy count has been set. This applies if
the "How to set default owning library for auto-created line item
items" setting is set to "use_setting".
