Monitoring policy creation foundation
Upgrde to xacml v2.0.0 release artifact. Some re-arrangement of classes. New class to support a common dictionary among the monitoring applications. I may move it to a common under the main since some of the values are shareable. Created application service provider, so the XACML main knows what policy types are pre-loaded and can report them back to the PAP. struggled with cucumber, which does not create TemporaryFolder although the documentation says its supported. Added a new Policy Finder specific to ONAP which does quicker job to load policies. Issue-ID: POLICY-1273 Change-Id: I4af15a64da3b42d48f29809710421b1649625adc Signed-off-by: Pamela Dragosh <pdragosh@research.att.com>
