Completed implementation of HandlenetServiceBean

- pulled up methods to AbstractIdServiceBean
- implemented methods of HandleNetServiceBean that still threw a NotImplementedException and were called somewhere

 Persistent Identifiers and Publishing Datasets
 ++++++++++++++++++++++++++++++++++++++++++++++
 
-Persistent identifiers are a required and integral part of the Dataverse platform. They provide a URL that is guaranteed to resolve to the datasets they represent. Dataverse currently supports creating identifiers using DOI and additionally displaying identifiers created using HDL. By default and for testing convenience, the installer configures a temporary DOI test namespace through EZID. This is sufficient to create and publish datasets but they are not citable nor guaranteed to be preserved. To properly configure persistent identifiers for a production installation, an account and associated namespace must be acquired for a fee from one of two DOI providers: EZID (http://ezid.cdlib.org)  or DataCite (https://www.datacite.org). Once account credentials and DOI namespace have been acquired, please complete the following identifier configuration parameters:
