Custom fields: Create UI permissions for Settings > Users > Custom Fields CRUD

As a FOLIO Systems Librarian
I want to control who at the library has the ability to CRUD custom fields
So that the data integrity of our FOLIO system is maintained.

Requirement : Create the following UI permissions

• Settings (Users) : Can create, edit, view, and delete custom fields
• Settings (Users) : Can create, edit, and view custom fields
• Settings (Users) : Can view custom fields

Acceptance criteria

Given I have been assigned the permission [Settings (Users) : Can create, edit, view, and delete custom fields]
When I go to Settings > Users
Then I should see the Custom Fields list
AND I should be able to create/edit/view/delete a custom field(s)

Given I have been assigned the permission [Settings (Users) : Can create, edit, and view custom fields]
When I go to Settings > Users
