Add new EnvProperties class
Added new class EnvProperties, which extends java.util.Properties and supports property values containing embedded environment variable references. Updated code to use this class to load svclogic.properties, and updated dmaap listener to use that class to load dmaap listener configuration. Issue-ID: SDNC-1482 Signed-off-by: Dan Timoney <dtimoney@att.com> Change-Id: I7538b719631d8c10c27d059aeb4f70ce92760ebd
