Update oparent version to 1.1.0

Update oparent version to 1.1.0

Directive from ONAP project that all repos should be updated.
Change vierified with a build with .m2 /org/onap cleared.

The test cases are updated becasue changing the oparent version changed the
order of test execution and tests failed due to the static data in PAPServices
not being cleared. Clearing of PAPServices data in those test cases is now
done in an @After method.

The test case in the test below has a test dependency:
ONAP-PDP-REST/src/test/java/org/onap/policy/pdp/rest/notifications/test/NotificationTest.java
depends on com.att.aft.dme2 version 3.1.200-oss

That dependency was added to the POM of ONAP-PDP-REST
