feat(policy): add unsafe attribute RPC db connectivity (#1022)

3rd PR for #115 

 - [x] reactivate (no cascade down)
 - [x] update definition name (and upsert fqn)
- [x] upsert name fqn changes from namespaces down and from attribute
definition down to values
 - [X] update rule (changes access)
 - [x] reorder of values (changes hierarchy)
 - [x] delete (cascading)
