Remove powermock to increase coverage
Removed powermock from the junit tests of these classes to increase reported sonar coverage: RESTfulPAPEngine BrmsGateway Typically added override methods to the classes under test, to replace the overrides originally provided by powermock. Also needed to add code to RESTfulPAPEngineTest to clear the XACML properties before the test ran. Modified to use the existing XACMLProperties.reloadProperties() method. Also modified PolicyNotificationMailTest to use a host/port that has no listener so that the test runs faster. Fixed some newly introduced sonar issues.
