From e173fc5ab13b095d8f70fd8a8d4d063adeba6e6b Mon Sep 17 00:00:00 2001
From: Jim Hahn <jrh3@att.com>
Date: Fri, 5 Jul 2019 10:52:20 -0400
Subject: Fix sonar issues in policy/endpoints

Sonar fixes, other than code coverage.  These changes are disruptive
and will likely cause breakage in a number of policy repos.
Renamed constants.
Moved constants/factories from interfaces to classes.

Change-Id: I182d50320aa6b53e383081af806c60dd2f806cbe
Issue-ID: POLICY-1791
