Is your feature request related to a problem? Please describe.

We don't want giving our staff ADMIN permissions, but they need to be able to add new option values without distracting us every time.

Describe the solution you'd like

Everyone authenticated should be able to manage option values. This can be also configured on a field level (e.g. "Who can manage option values: Everyone | Only admins").

Describe alternatives you've considered

See above.
