Update git submodules

* Update docs/submodules/ccsdk/parent.git from branch 'master'
  to 54fc4ce488bbd26b86fddc26c6e2af32ee1d7c15
  - Add missing distributionManagement section

    Add missing distributionManagement section to new BOM pom files.  This
    is needed because this is not specified in ONAP settings.xml - it must
    be explicitly set in each pom.xml OR inherited from a parent pom.
