Update git submodules

* Update docs/submodules/snaps from branch 'master'
  - Merge "openstack: nova_utils_tests: Use API timeout argument instead of sleep()"
  - openstack: nova_utils_tests: Use API timeout argument instead of sleep()
    
    On slow environments, time.sleep(10) is not enough for attach/detach API
    calls to propage properly leading to failures like the following one
    (reduced api_check test)
    
    2018-01-31 18:53:19,297 - functest.ci.run_tests - INFO - Running test case 'api_check'...
    2018-01-31 18:54:27,434 - functest.ci.run_tests - INFO - Test result:
    
    +-------------------+------------------+------------------+----------------+
    |     TEST CASE     |     PROJECT      |     DURATION     |     RESULT     |
    +-------------------+------------------+------------------+----------------+
    |     api_check     |     functest     |      01:07       |      FAIL      |
    +-------------------+------------------+------------------+----------------+
    
    We can workaround this by using the nova_utils.{de,at}tach_volume}
    'timeout' argument to wait up to 2 minutes for the attach/detach call to
    complete. This doesn't affect normal exception whilst it helps get the
    test going on slow systems. WIth this change, the api_check (reduced
    test) passes as follows:
    
    2018-01-31 18:48:35,469 - functest.ci.run_tests - INFO - Running test case 'api_check'...
    2018-01-31 18:50:56,705 - functest.ci.run_tests - INFO - Test result:
    
    +-------------------+------------------+------------------+----------------+
    |     TEST CASE     |     PROJECT      |     DURATION     |     RESULT     |
    +-------------------+------------------+------------------+----------------+
    |     api_check     |     functest     |      02:20       |      PASS      |
    +-------------------+------------------+------------------+----------------+
