Support required enum fields - a.enum().required() #570
Description
Is your feature request related to a problem? Please describe.
It is currently not possible to mark an enum field as required.
Describe the solution you'd like
Support calling .required() as in a.enum().required() to mark the field as required.
Describe alternatives you've considered
Replacing any required enum with a required string and manually validating and restricting the values with a custom resolver. This would mean that I lose all benefit of enums. This would mean I would now have more code to manage just to implement an enum.
