Update git submodules

* Update docs/submodules/functest from branch 'master'
  - Switch from generate_report to PrettyTable
    
    run_tests.py now relies on PrettyTable as most of the openstack clients.
    generate_report.py and its related unit tests are simply removed.
    
    It sets padding_width=5 in testcase.py too to conform with
    run_tests.py.
    
    Now report is printed in every case.
