  to reduce the footprint
- brought the latest packages except zip lib
- added package-lock.json to freeze the dependencies
- latest log4js - change of configuration file format
- fixed call to cloudify API /node-instances
  added &_sort=id to make the pagination consistent
- changed uuid/v4 to uuid.v4() to avoid the deprecation warning
- unit test
  = coverage by nyc now
  = on policy API - assert all expected nock calls are done
- integration testing with the latest policy-handler (DCAEGEN2-1851)
  and the new policy-engine is requested
