Ability to require Indication of Use required for all PRN frequencies Merged

Since a prn indication of use is required for all orders that have a prn frequency, we need the ability to set indication required for meds with all of those frequencies. We could still set the possible indications on the medication itself, but only require it if it has a prn frequency. Setting it on the medication would require it every time it is ordered, which is required some meds like antibiotics, but not all. For other meds, we only need to required the indication if it is ordered prn.
