Possible to find unused CVL values

How: A way to easy find all unused CVL values to be able to decide if they are old/obsolete and should be deleted, in order to maintain and keep a relevant data model.

Why: To keep a good quality of the data model and not risk old/obsolete values to be used shown in the lists in the UI.

For Who: As an admin/product owner/system owner/inriver partner. (Possible to control access via permission?)

Impact: To make it easier to keep a relevant data model and increase user experience.

Additional context:

It would be nice to be able to do a search that gives me CVL values that are currently unused (i.e. not used on any entity). Either by specifying a specific CVLId or search among "All CVL's".

In the search result I should get:

-Information about the CVLId of the unused value (Key, Index, Deactivated, Name (in all locales)).

-The FieldTypeId(s) where the CVL is applied/used

-The EntityType(s) where that CVL is used in any field(s).

This will provide great information in the context of deciding whether the CVL value should be deleted or not and what impact that removal may have for the customer/users.
