Update return value from postbuildscript

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
