Concept API/ Scripting behavior is changed for required custom field for creating and editting items

Create Item:

Create item is working based on configured parameter as per following
SETTINGS  => SETUP & CONFIGURATION => parameters => Advanced =>  WHEN VALUE OF REQUIRED CUSTOM FIELD IS NOT FILLED

Options
a) Write an error to the log, allow the data to be saved
b) Write validation log and stack trace to the log, allow the data to be saved
c) Throw an exception, no longer allows invalid values through the API

Edit Item:
In case of edit item it will always throw an exception if we try to edit item without filling value of required custom field.
