Addition of Active-Standby Feature
Patch 1: Adds the active-standby feature to drools-pdp. This feature provides the state control of the drools-pdp nodes controlling failover with a site and across sites. Patch 2: Resolve merge conflict in packages/install/pom.xml and pom.xml. Patch 3: Resolved comments from Pamela Dragosh and Jorge Hernandez. Issue-ID: POLICY-156 Change-Id: I922b3d5d8a464006e9675924bcbc7409d68c08d5 Signed-off-by: Kevin McKiou <km097d@att.com>

+ * "pause" the processing in ActiveStandbyFeature class. I think we could "pause"
+ * it by calling globalInit() which will, I think, restart it. So long as it
+ * does not create a new instance, it will force it to go through an initialization
+ * cycle which includes a "pause" at the beginning of proecessing. We just must
+ * be sure it does not create another instance - which may mean we need to add
