Adding optimization application finish guard
Created Optimization application and created a translator for it. The translator makes an assumption that OOF wants to query on policyScope and policyType properties. Rearranged some of the test code for re-usability. Guard policies are now creating for frequency limiter and min max. Probably could use some clean up. Upgraded to xacml 2.0.1 to include a fix for handling null attribute values. Added some code to test missing values. Issue-ID: POLICY-1273 Change-Id: Ia3dbfa992bbe0cbb5aa294c38aa2aff430a3230a Signed-off-by: Pamela Dragosh <pdragosh@research.att.com>
