Update git submodules

* Update docs/submodules/policy/parent.git from branch 'master'
  to c80213e91c20dca8794a7d7540d9afb876b6d693
  - Add RE2J in lieu of java.util Pattern

    Sonar complains about java.util Pattern usage when the pattern
    has quanitifiers like "*" or "+".  It suggests using RE2J instead.
    Added that to the parent pom - hope it doesn't have licensing issues.

    Issue-ID: POLICY-2305
