Fix sonar issues in policy ONAP logging

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.
Also fixed remaining checkstyle issues, which was equally disruptive,
as it required renaming of methods and classes.
Split out Onap config properties from EELF config properties, in
case changes are made in the future such that Onap properties can
no longer subclass from EELF properties (e.g., if EELF properties are
converted from a interface to a utility class with a private constructor).
Attempted to eliminate some duplicate blocks of code by refactoring
out common methods.
