This sub-task is for the API improvements needed to support the new Packs to Ship (V) requisition field. The APIs should be updated to support admins configuring this field on their requisition template for their programs, and then to allow users to initiate and save/submit a requisition with this field on it.
in the APIs for configuring a requisition template, this new field can be added into the requisition template (by an admin with permissions to configure the template for their program)
if this field is NOT configured/associated to a requisition template, it does not appear on the requisition form
the field can be configured with a display order that controls where it appears on the requisition
in the APIs for initiating and saving a requisition, if this field is part of the template, then this field appears on the requisitions. Its display order should be based on the requisition template.
Following reference data endpoints need to be available
Pack rounding threshold : non-negative integer
round to zero : boolean
