Update git submodules

Update git submodules

* Update docs/submodules/policy/engine.git from branch 'master'
  to dbfa1570cd26d19b346287a6fb06f2d8a03f4a06
  - Use lombok for data objects

    Removing lines to see if this will bump coverage. Some sonar
    for Junit tests and missing coverage.

    My next task will be to re-use some of this duplicate code
    for these object types and the controllers.

    Trailing spaces for patch #3.
