Update git submodules

* Update docs/submodules/integration/test from branch 'master'
  to ffa04403057d7d354ca0a2261b6bc7eabf5aeb1d
  - Fix for OPNFLWPLUG-1022 requires Topology Manager

    module to register for singleton clustering service.
    That introduces application entity in the EOS output.
    In the current cluster tests, after disconnecting all
    the OpenFlow devices, test checks that no openflow
     device should have owner, by grepping the "member"
    string, and expect that it should be 0. After
    introducing topology manager entity, EOS output
    will always have one entity with all the 3 controllers
    as a candidates, so greppign the "member" string
    will always return 3. This patch take care of this
    change."
