Update git submodules

* Update docs/submodules/releng from branch 'master'
  - Define parameters for triggering jobs
    
    In
    https://wiki.jenkins.io/display/JENKINS/Plugins+affected+by+fix+for+SECURITY-170,
    it indicates that:
    
        only build parameters that have been explicitly defined in a job's
        configuration will be available by default at build time. Any other
        arbitrary parameters added to a build by plugins will not be
        available by default.
    
    It has been tested in sandbox.opnfv.org that only defined parameters can
    be passed to the triggered jobs.
    
    For parameters required by TESTAPI are common to all the projectes,
    including installers, Functest, and Yardstick, it is convenient to
    define a common macro and used by others.
