Update git submodules

Update git submodules

* Update docs/submodules/policy/engine.git from branch 'master'
  to f36e53a3637e1204a42491ec0eeed7b3c763f681
  - More sonar cleanup and line consolidation

    Missing javadoc and some variable naming to remove consecutive
    capitlization of letters.

    120 line width reduction
    Missing curly braces
    Moving variables due to distance requirements
    Add missing rawtype suppression or useless ones
    There are some null return statements that are useless

    Started doing some combining of lines at the risk of making the
    code even more unreadable than it already is.

    Started addressing some nested if's.

    I see opportunity for a lot of common code to be combined or
    put into a base controller or utility method.
