Add a new module for common handling of Admin Queue related logic. Start by a helper for error to string conversion. This lives inside libie/, but is a separate module what follows our logic of splitting into topical modules, to avoid pulling in not needed stuff, and have better organization in general. Olek suggested how to better solve the error to string conversion. It will be used in follow-up patches in ice, i40e and iavf.
