Update git submodules

* Update docs/submodules/policy/engine.git from branch 'master'
  to f4ec47c009cdc385a7efed02dda5d26f2ec31b57
  - JUnit/SONAR/Checkstyle in ONAP-REST
    
    First batch of JPA pojos Lombok'd and some missing coverage updated
    
    I'll be interested to see how Lomboking code shows up in SONAR, I have
    not added much JUnit here but I have reduced a good bit of source code,
    let's see what happens.
