Update git submodules

* Update docs/submodules/functest from branch 'stable/euphrates'
  - Bug fix: vping_userdata test status was not properly reported
    
    vping_base is calling vping_userdata
    vping_user data could return only EX_TESTCASE_FAILED or EX_OK
    by default vping_base always returns EX_OK (based on self.result=100..)
    it returned EX_RUN_ERROR only if upper class report EX_RUN_ERROR
    
    that is why vping_userdata was always PASS even if the trace "Ping OK"
    cannot be retrieved from the Nova console
    
    it seems that when running the vping_userdata, we systematically got
     Failed to read iid from metadata
