As a ONAP developer, I would like to use the common implementation of RestServer provided in policy/common repo in apex-pdp (like all other components in policy framework). And remove the local implementation.

Current one is here - https://github.com/onap/policy-apex-pdp/blob/master/services/services-onappf/src/main/java/org/onap/policy/apex/services/onappf/rest/ApexStarterRestServer.java
