From 506267bf7e9d961f1a6b2a989ee8a23ca67b9d61 Mon Sep 17 00:00:00 2001
From: Charles Cole <cc847m@att.com>

Subject: Add support for AAI Named Query error handling

Errors from AAI after a Named query now throw an AAIEXception.  This is
caught in the template to allow the resources to be removed from memory
and a final failure to be thrown.

Issue-ID: POLICY-314
Change-Id: I319d29ef537b2d01ca288622aac1d9dbbe05f5eb
