2.2.0 onap-dcae-dcaepolicy-lib - refactoring

- removed the following obsolete and unused features
  = removed policy apply_order parsing
  = removed policy sorting
  = removed policy config merge into app-config
  = removed tracking fields in app-config affected by policies
  = removed getting config from config.content on microservice
  = removed org.onap.dcae from license text
- simplified the logic flow without policy sorting
    and without getting policy configs
- removed the option to pass the policy configs to plugins
    = only passing the policy bodies to be included
        into the policy-notification message
- refactoring to reduce function complexity according to sonar
- reduced the unit tests to match the new code - coverage is 80%
