Update git submodules

* Update docs/submodules/releng from branch 'master'
  - Update return value from postbuildscript

    PostBuildScript plugin's result affects Jenkins pipeline, so we should
    return the original job running status in the postbuildscript in the end

    Update macros:
    1. from $POD_NAME to $NODE_NAME
    2. from $SCENARIO to $DEPLOY_SCENARIO
    2. {installer} to $INSTALLER_TYPE for {installer} is not existed in
       trigger job
    3. add parameters definition for they can not be used in trigger jobs by
       predefined-parameters
    4. missing TIMESTAMP_END
