Custom Field UI visibility option "Hidden if unset" #12597
Description
NetBox version
v3.5.1
Feature type
Change to existing functionality
Proposed functionality
On the custom-fields edit page, add "Hidden if unset" option to the "UI visibility" selection, and on the object view page, if that's set on definition of a custom field and the field is unset hide that custom field (instead of showing -).
Use case
We have devices managed by a few groups with different needs, and we're using custom fields to help with some of that. This would keep the display of a device (or virtual-machine) cleaner when custom fields aren't used on a specific device.
Use cases are similar to #12423, but I suspect the code would be much simpler.
