Add 'use_template' option for job parameters in Workflow.groovy

- Add "use_template" option to assemble different artifact paths
  into a single job parameter, for example:

    REPORTS_LIST:
      type: TextParameterValue
      use_template: |
        REPORT_SI_KAAS_BOOTSTRAP: \$REPORT_SI_KAAS_BOOTSTRAP
        REPORT_SI_KAAS_UI: \$REPORT_SI_KAAS_UI
        REPORT_KAAS_UI: \$REPORT_KAAS_UI
