Delete a custom role.

Delete a role with the given UID, and it’s permissions. If the role is assigned to a built-in role, the deletion operation will fail, unless force query param is set to true, and in that case all assignments will also be deleted.

You need to have a permission with action roles:delete and scope permissions:type:delegate. permissions:type:delegate scope ensures that users can only delete a custom role with the same, or a subset of permissions which the user has. For example, if a user does not have required permissions for creating users, they won’t be able to delete a custom role which allows to do that.
